For

SpinQuest

...

it

...

will

...

be

...

difficult

...

to

...

get

...

the

...

positioning

...

of

...

the

...

target

...

perfectly

...

aligned

...

with

...

the

...

beam.

...

This

...

is

...

because

...

all

...

fiducials

...

that

...

we

...

can

...

get

...

while

...

the

...

system

...

is

...

warm

...

and

...

open

...

will

...

change

...

once

...

we

...

are

...

running

...

with

...

liquid

...

helium.

...

We

...

have

...

X,

...

Y

...

positioning

...

measured

...

from

...

averaged

...

vertex

...

reconstruction

...

but

...

this

...

takes

...

at

...

least

...

1

...

month

...

of

...

data

...

to

...

produce,

...

and

...

this

...

will

...

only

...

give

...

the

...

mean

...

with

...

a

...

very

...

large

...

variance.

...

This

...

means

...

we

...

need

...

to

...

get

...

the

...

information

...

we

...

need

...

from

...

the

...

survey

...

and

...

the

...

final

...

set

...

of

...

surveys

...

will

...

need

...

to

...

contain

...

some

...

cold

...

target

...

information.

...

The

...

precision

...

in

...

the

...

target

...

cell

...

to

...

beamline

...

positioning

...

needs

...

to

...

be

...

good

...

to

...

mitigate

...

large

...

absolute

...

errors

...

while

...

running.

...

This

...

is

...

estimated

...

to

...

be

...

on

...

the

...

sub-millimeter

...

level

...

(based

...

on

...

simulations

...

being

...

confirmed).

...

There

...

are

...

several

...

factors

...

that

...

can

...

lead

...

to

...

false

...

asymmetries

...

relating

...

to

...

this

...

precision.

...

There

...

can

...

be

...

a

...

bias

...

produced

...

in

...

the

...

detector

...

if

...

there

...

the

...

beam

...

is

...

off

...

center.

...

There

...

can

...

be

...

less

...

polarized

...

scattering

...

if

...

the

...

beam

...

is

...

not

...

aligned

...

and

...

missing

...

part

...

of

...

the

...

target

...

(beam

...

profile

...

dependent,

...

also

...

being

...

checked).

...

There

...

can

...

be

...

greater

...

scattering

...

off

...

the

...

aluminum

...

ladder

...

on

...

one

...

side

...

as

...

compared

...

to

...

the

...

other.

...

Most

...

of

...

these

...

manifest

...

from

...

X

...

being

...

off

...

but

...

if

...

Y

...

is

...

off

...

over

...

1

...

mm

...

then

...

the

...

same

...

issues

...

start

...

to

...

manifest

...

with

...

the

...

ladder

...

as

...

well

...

but

...

this

...

may

...

not

...

result

...

in

...

false

...

asymmetry

...

and

...

only

...

result

...

in

...

additional

...

heat

...

load

...

to

...

the

...

coils.

...

During

...

our

...

discussions

...

with

...

the

...

survey

...

crew

...

it

...

was

...

suggested

...

to

...

install

...

transparent

...

windows

...

so

...

we

...

could

...

do

...

an

...

optical

...

survey

...

on

...

the

...

magnet

...

and

...

target

...

cells

...

while

...

cold.

...

This

...

would

...

be

...

great

...

to

...

do

...

but

...

I

...

do

...

not

...

think

...

this

...

is

...

possible

...

at

...

FNAL.

...

I

...

don't

...

believe

...

we

...

would

...

ever

...

pass

...

a

...

safety

...

review

...

to

...

do

...

that.

...

The

...

next

...

best

...

option

...

is

...

to

...

do

...

surveys

...

using

...

liquid

...

nitrogen.

...

We

...

could

...

calculate

...

the

...

level

...

of

...

contraction

...

for

...

both

...

LN2

...

and

...

LHe.

...

We

...

can

...

then

...

measure

...

the

...

contraction

...

during

...

an

...

open

...

system

...

survey

...

with

...

LN2

...

in

...

the

...

magnet

...

and

...

in

...

a

...

nose

...

with

...

a

...

window

...

on

...

it.

...

The

...

set

...

of

...

survey

...

would

...

go

...

like

...

this:

...

 

1.)

...

Survey

...

on

...

dock

...

with

...

fully

...

open

...

system

...

(no

...

nose,

...

no

...

nitrogen

...

shield,

...

no

...

beam

...

windows).

...

Survey

...

the

...

magnet

...

aperture,

...

the

...

target

...

insert

...

along

...

X

...

only,

...

and

...

the

...

outside

...

fiducials

...

(can

...

and

...

top

...

flange).

...

The

...

primary

...

goal

...

of

...

this

...

survey

...

is

...

to

...

generate

...

fiducials

...

on

...

the

...

can

...

and

...

top

...

flange

...

to

...

help

...

align

...

when

...

going

...

into

...

position

...

in

...

the

...

cave.

...

This

...

part

...

of

...

the

...

survey

...

should

...

be

...

able

...

to

...

be

...

measured

...

with

...

error

...

at

...

less

...

than

...

0.5

...

mm.

...

The

...

fiducial

...

on

...

the

...

can

...

is

...

meant

...

to

...

use

...

to

...

align

...

the

...

top

...

and

...

bottom

...

to

...

our

...

best

...

precision.

...

The

...

tolerance

...

of

...

the

...

drawings

...

is

...

0.5

...

mm.

...

 Use

...

the

...

leveling

...

pads

...

to

...

level

...

the

...

magnet

...

on

...

the

...

dock

...

before

...

survey.

...

This

...

survey

...

can

...

be

...

use

...

to

...

check

...

the

...

variation

...

when

...

leveled

...

and

...

re-leveled

...

or

...

if

...

the

...

magnet

...

is

...

plumb

...

not

...

the

...

top

...

flange

...

is

...

slightly

...

off

...

level.

...

Working

...

on

...

the

...

dock

...

for

...

this

...

survey

...

will

...

have

...

the

...

advantage

...

of

...

space

...

unlike

...

in

...

the

...

cave.

...

We

...

can

...

also

...

flip

...

the

...

insert

...

and

...

check

...

target

...

cell

...

up

...

stream

...

and

...

down

...

stream

...

differences.

...

2.)

...

Survey

...

in

...

cave

...

using

...

LN2

...

in

...

nose

...

and

...

magnet.

...

This

...

would

...

be

...

a

...

partly

...

open

...

survey

...

with

...

a

...

special

...

nose

...

put

...

on

...

with

...

transparent

...

windows

...

on

...

either

...

side

...

for

...

optical

...

survey.

...

The

...

nitrogen

...

shield

...

and

...

beam

...

widows

...

on

...

the

...

vacuum

...

are

...

left

...

off

...

for

...

this.

...

This

...

survey

...

in

...

the

...

cave

...

will

...

be

...

of

...

the

...

magnet

...

aperture,

...

the

...

target

...

insert

...

along

...

X,

...

Y,

...

Z,

...

and

...

the

...

outside

...

fiducials

...

(can

...

and

...

top

...

flange

...

and

...

reference

...

locations

...

in

...

the

...

cave).

...

Crosshairs

...

will

...

be

...

use

...

in

...

the

...

front

...

and

...

back

...

of

...

the

...

target

...

cell

...

to

...

help

...

determine

...

degree

...

of

...

twisting

...

in

...

the

...

cell.

...

Cross

...

hairs

...

in

...

the

...

can

...

windows

...

can

...

also

...

be

...

use

...

to

...

set

...

the

...

rotational

...

alignment

...

of

...

the

...

can.

...

The

...

target

...

insert

...

carbon

...

fiber

...

is

...

not

...

expected

...

to

...

contract

...

very

...

much

...

but

...

the

...

aluminum

...

ladder

...

can.

...

The

...

primary

...

goal

...

of

...

this

...

survey

...

is

...

to

...

compare

...

to

...

calculations

...

of

...

contraction

...

and

...

measure

...

positioning

...

of

...

target

...

cell

...

with

...

respects

...

to

...

magnet

...

aperture

...

and

...

also

...

with

...

respect

...

to

...

the

...

beamline.

...

There

...

should

...

be

...

a

...

hard

...

stop

...

setup

...

on

...

the

...

actuator

...

that

...

positions

...

the

...

top

...

target

...

exactly

...

in

...

the

...

beam

...

line

...

(to

...

test

...

repeatability

...

of

...

the

...

string

...

potentiometer

...

and

...

gears).

...

We

...

also

...

need

...

to

...

take

...

the

...

stick

...

out

...

and

...

few

...

times

...

and

...

test

...

the

...

deviation in reproducibility in target cell shifts and bends.
This will take two surveys to do since we will need to machine the piece for
this hard stop after this first cold survey measurement.  In order to do this
the actuator and motor should be installed so we can move up and down with
reasonable repeatability.  This repeatability can also be tested during this survey.

The drawings indicate a change of 4.5 mm up when cold.

3.)

...

Put

...

in

...

hard

...

stops

...

and

...

re-survey.

...

This

...

will

...

be

...

adding

...

a

...

shim

...

to

...

the

...

hard

...

stop

...

that

...

already

...

exists.

...

Here

...

we

can

have

...

the

goal

...

of

...

.25

...

mm

...

target

...

centering

in

and

measure

a

of

using

cross

hairs

...

in

...

Z.

...

4.)

...

An

...

X-ray

...

survey

...

while

...

cold

...

would

...

be

...

the

...

next

...

step

...

if

...

possible.

...

We

...

may

...

not

...

needed

...

it

...

if

...

we

...

achieve

...

good

...

results

...

from

...

the

...

first

...

3.

...

It

...

may

...

also

...

be

...

possible

...

to

...

use

...

phosphine

...

graph

...

paper

...

to

...

check

...

beam

...

position

...

on

...

a

...

special

...

target

...

insert

...

without

...

depending

...

on

...

the

...

magnet

...

or

...

nose

...

having

...

LHe

...

in

...

them.

...

 Or use

...

something

...

that

...

discolors

...

or

...

burns

...

in

...

the

...

beam

...

so

...

we

...

can

...

make

...

an

...

insert that will be use over the experiment to check position.
