LabView Vi's & associated information

Steps of VI Availability (Tentative)

1. A few simple VIs for readout and configuration.  It is to confirm that the device can be controlled with LabVIEW.
2. A complete set of VIs for readout and configuration.  Each VI should perform one function of the device.
3. VIs for user interface. 
4. VIs for continuous measurement.
5. VIs for continuous logging.
6. Note that an integrated user interface (like PDP) for all the devices that we use will be considered in a future.  We could use DQMH or CML DQMH.

Note about installation:

• The biggest issue is where to put MKS 690 1000 Torr. Ideally it should be close to the 100 Torr one
• Please consult with Dustin to make sure about the final location
• Sensor number 3 (He3) and 8 (Measuring LN2 reservoir) in the google docs and sheets above can not be installed not (waiting pipe/line installation). The rest could be installed
• Sensors number 10 and 11 are LANL sensors. Please consult Misha to make sure which are the correct sensors since in the root, there are several other sensors from oerlikon
• Please consult Ernesto for the current location of sensors and long cables

• For the annealing system we should have the analogue setup be entirely independent of the other system, this will require 4 sensors. Two for the Waqar system and 2 for the Henery system, if possible.
• All other, ~20 sensors should be setup with the same type of DAQ that Kenichi is testing unless we determine it is not suitable regarding temperature dependent error. The error budgets are different for several of these, but Magnet coils is by far the most critical low relative error requirement. So, if it looks like this setup will work there it will work everywhere.
• Questions/discussions
  • We need four of MCC E-TC, given the number of TCs at present.  Can we decrease N of TCs by one or two?
  • We might put one of MCC E-TC at the magnet rack, if some TCs are closer to the magnet rack than the slow control rack.

Overall Computer+Program Configuration

This section is to discuss and share the overall configuration about computers and programs that we expect.  The required spec of each program might depend on this configuration.

• Target computer @ control room
  
  • BOS/EOS/Spill-ID (which detects the hardware BOS/EOS signals to issue the software BOS/EOS/Spill-ID info)
  • Cryogenic control panel (https://github.com/uva-spin/e1039-target-controls/tree/master/Cryo-Control)
  • Microwave frequency calibration (https://github.com/uva-spin/e1039-target-controls/tree/master/Motor%20controller)
  • VIs/projects of all standalone devices
    • To be listed...
• NMR computer @ cryo platform
  
  • PDP (https://github.com/uva-spin/e1039-target-controls/tree/master/PDP) — Misha found that the measurement accuracy varies with the number of sweeps/event.  It has to be confirmed, to determine how we configure the number and if we have to change it on spill vs off spill.
• Communication between the computers
  • The NMR computer needs BOS/EOS/Spill-ID in real time.  What are the limits of latency/jitter times???
  • If the latency of the TCP/IP communication (<1 ms inside LAN?) meets the requirement, it can be used.
  • If not, probably we have to move the "BOS/EOS/Spill-ID" function to the NMR computer.
• Other components or functions??
