Discussion of Readout architecture with Markus and Jorgen
Jorgen proposes writing a RCD_empty package into which we can add TRB specific code
A TRBscope program should be written to capture data from the TRB
The TRBscope can explore the data format and understand handling of UNIX sockets
A TRBemulator could be written to send arbitrary data at arbitrary times, or replay a sequence of packets from the TRB
Ultimately the TRBscope code should be integrated into the RCD_empty package to form an RCD_TRB package that can run in the BL4S data-taking partition

Working with Elena Zarkh
Set up DAQ PC and electronics
Dual timer is tricky to start up as a pulse generator
Used switch box to view test pulses from front end electronics
Found that the TRB needs a LVDS trigger, when disconnected it free runs to around 40kHz
The trigger box (based around one of the level converter cards) accepts TTL level signals and outputs LVDS across all channels, however some seem to be flipped or offset - check trigger box outputs when setting up; the outputs are on a pin header so we reused the switch box to probe the pin header, connecting it to a scope over LEMO cables
The discriminator for one of the channels had a very narrow pulse width, killing the coincidence rate - we adjusted this up to ~100ns
We measured the coincidence rate of the scintilators to be just below 10Hz
A small test run did not collect any meaningful statistics
Overnight run started ~21:50

TRB

Digitisation is done with the TRB[2] system. The TRB has 4 HPTDC chips[1]. The TRB configuration has a resolution of 100ps and a readout period of up to several microseconds. The data is zero suppressed and forwarded to a PC over a network. The PC hostname is styxbn.cern.ch and the user credentials are listed on the SysAdmin page.
Added:
>
>
The PC acts as DHCP server for a private network (192.168.0.*) on which the TRB resides. The PC also hosts the filesystem for the TRB from it's /var/diskless/ directory. Control and readout scripts are located in ~styx/bin/.

Adaptation for BL4S

For BL4S, we might use the front end cards and digitise the signals with standard VME TDCs. Alternatively we could use the TRB and build events by embedding the TRB packets. We will need to understand the data volume of the system in designing the ReadOutSystem.

List of Issues

  • Trigger does not work properly: Signal is too low?
Line: 45 to 57
 
  • The reason of the wiring crossover : connection from FE boards to STYX box?
    • This is due to the fact that the TRB can take 31 signals on each connector and the 32nd channel is for the trigger. It is best if the outermost straws are not rad out. However, these straws are one something like the 4th readout channel - this can be seen in the mapping file. Steffen calls this the “fudge cable”!

  • Pulse width of one of the PMT's is too narrow ?---Need to be investigate!
 
    • This is in fact design. The larger PMT has a wider signal after the discriminator and the threshold for it is set higher. The small PMT has a lower threshold (almost in the noise) and should have a narrow signal. This, according to Steffen, is the standard way of making such coincidences. He was also surprised at the low rate though. Maybe one really has to scan the scintillator HV again, adjust the thresholds, check the timing etc. more carefully.
  • 2 out of 6 FE boards with not enough events ?
    • It has been seen in the past that this can be caused by the gas not being on long enough. Given that you turned on the gas the week before Elena came, it is probably not the cause, but it is something one can check by taking data at different times after the gas has been turned on.

 For BL4S, we might use the front end cards and digitise the signals with standard VME TDCs. We will need to understand the data volume of the system in designing the ReadOutSystem.

The detector element at CERN is mounted horizonatally to collect data from cosmic rays. For installation into the BeamLine, we will need a vertical mounting solution.

Visit SR1 to see CERN's STYX module.

Resources

 The StrawTracker modules are used in the Straw Tube Young student eXperiment (STYX). Lots of information on their setup is available on their project pages.

 The detector requires ~ 2kV power supplies.

The front-end cards will require low voltage supplies.

DAQ

16 channel front end cards are available with ASDQ chips. These perform descrimination against an input threshold voltage (~<1V). They output multiplexed timing signals, 200ns per straw, for a total readout period of 3.2us.

Digitisation is done with the TRB system. This has a resolution of 100ps and a readout period of upto several microseconds. The data is zero suppressed and forwarded to a PC over a network.

For BL4S, we might used the front end cards and digitise the signals with standard VME TDCs. We will need to understand the data volume of the system in desining the ReadOutSystem.

Electrical
