To Do Lists

11-6-2018

• Check on health of the NIM crate and it's various output signals
• Do the same thing for the Counting House
• Check on/implement the helicity timing that is sent via the Counting House's Trigger Supervisor

11-5-2018

• We should look at file sizes as a function of time.
• We should keep messing with the parameters.
• We should take the TS busy out and use that in the scalers too (needs a non-binary ECL cable and translation).
• We should use the java monitorGui to look at the data flow.

11-2-2018

• Go into the Injector (and CRL) and map out the timing.
• Redo the tests with -q, -n, -r, and CHUNK size to see what affects the ET client analyzer's deadtime.

11-1-2018

• We can confidently use the Cavity BPM signals in the Parity DAQ for future tests now (we have verified ADC functionality for those channels).
• A potentially confounding issue with SEE BPM B was resolved. There was a mirroring about the ym-xp axis that was fixed by swapping the wiring of yp and xm.

9-10-2018

• Verify the RAM stays by doing a hardware power cycle
• Replicate battery replacement in all other ROCs to prevent this issue from reappearing (Cameron has the batteries)
• Replace the HAPTB DAC to TI module twisted pair connection
• Add HAPPEX Timing Board to Injector
• Test all ADCs in Injector
• Make a bank for all ADCs

7-31-3018

• Replace the NIM crate
• Rewire everything in the Injector DAQ
• Label everything
• Write out a diagram of the logic and the channels

7-30-2018

• Add HAPPEX Timing Board to Injector
• Test all ADCs in Injector
• Make a bank for all ADCs

7-29-2018

• Perfect and better justify parameters in Ramp testing function
• Check if something like int = 2 and conv = 0 is actually a more suitable gain setting for HAPPEX ADCs
• Put all of the DAQ software into a JeffersonLab repository and track it adequately
• Develop a similar ramping function but to use a constant DAC value and systematically scan the gain settings to understand the linearity, starting points, and relative significance of Integrator and Conversion gains for HAPPEX ADCs
• Do the QWeak ADCs in the Injector and verify issues with the ones in the Counting House + figure out how to test the Counting House HAPPEX ADCs
• Make a map of all channels and logic
• Characterize and test all scaler channels

7-28-2018

• Perfect and better justify parameters in Ramp testing function (and separate it out into a specific ramp-testing .crl file to avoid messing with the main Prex_ts.crl functionality)
• Move the RJ45 cable to a better location on the RHRS, with more slack and less likelihood of getting in the way of other people\
• Check if something like int = 2 and conv = 0 is actually a more suitable gain setting
• Understand the nature of "saturation", why signals over 5V are suitable if the gain is low enough, and what non-linearities arise near saturation
• Put all of the DAQ software into a JeffersonLab repository and track it adequately
• (JAPAN?) Develop a similar ramping function but to use a constant DAC value and systematically scan the gain settings to understand the linearity, starting points, and relative significance of Integrator and Conversion gains
• Learn how to tweak and characterize QWeak ADCs (begin with RHRS QWeak ADCs)
• Do the LHRS, Injector, and Counting House

7-27-2018

• Test ADCs and continue in todo list
• Perfect and better justify parameters in Ramp testing function (and separate it out into a specific ramp-testing .crl file to avoid messing with the main Prex_ts.crl functionality)

Wish List

Wish list for DAQ Test Setup in TEDf building

• 2 Swivel Chairs
• A portable toolbox
• A raspberry pie to practice on, and maybe also to use as a portable DAQ monitoring computer (instead of needing a personal laptop)
• Long Twisted Pair cables
• A portable oscilloscope
• A second small (shallow) VME crate (I checked in TEST lab storage area and none were clearly visible)
• Batteries (for pocket pulser, VME ROCs, and AA and AAA for battery signals)
• LEMO/BNC connectors and T's and 50 ohm resitors
• LEMO and BNC cables of various lengths, including at least a couple ~10 meter ones for LHRS DAQ usage
