TURBO

Introduction

• TURBO is a stand alone portable Control and Data Acquisition platform for the VFAT front end ASIC.
• It has been developed on the basis of the Totem Test Platform (TTP) used for testing the TOTEM hybrids equipped with VFAT chips.
• Each TURBO board can be interfaced with 8 VFATs.
• TURBO is controlled by a PC running LabView via USB interface.
• LabView softwares have been developed for VFATs control, standard calibration scans (threshold, calibration pulse, latency ), Data Acquisition and Quality Monitoring.
• Analog readout

Why we use it

• Portable
• User friendly
• "Real Time" response in order to understand what's going on
• Capability of DAQ for small/medium size system
• Fast

TURBO Software Structure

The TURBO Software is organized in three steps:

• TURBO CONTROL to control and test (➜ TURBO-CTRLXXXXXX.vi)

show TURBO CONTROL hide TURBO CONTROL

• DATA ACQUISITION (DAQ) (➜ TURBO-DAQXXXXXX.vi)

show DATA ACQUISITION (DAQ) hide DATA ACQUISITION (DAQ)

• DATA QUALITY MONITORING (DQM) (➜ TURBO-DQMXXXXXX.vi)

TURBO CONTROL step by step

• In TURBO REGISTER
  • Initialize DAQ
  • Write/Read TURBO Registers

• In VFAT REGISTER
  • Write/Read ➜ button WRITE

• In SIMPLE ACQUISITION
  • From here we can set threshold and latency

• In THRESHOLD SCAN
  • Select INTERNAL TRIGGER
  • Start (OUT OF THE SPILL)
  • Determine correct Threshold on TURBO 0 VFAT 1,4 ,5,6,7
  • Determine correct Threshold on TURBO 1 VFAT 1,4 ,5,6,7
  • Determine correct Threshold on TURBO 2 VFAT 1,4 ,5,6,7

* In CAL PULSE LATENCY SCAN

• In BEAM LATENCY SCAN
  • Select EXTERNAL TRIGGER
  • Start whenever we want (WE NEED THE BEAM)
  • Determine correct latency for peak position on histogram (rightone) typically between 20 and 40
  • Make the XML file according with values you measured

• IN VFAT REGISTER XML
  • Load VFAT registers from XML file
    • Choose your file

show VFAT REGISTER XML hide VFAT REGISTER XML

• IN SBIT
  • QUSB (First)
  • VFAT1
  • S1
  • SB: Write/Read SBIT
  • Read/Write SBIT gaps

show SBIT hide SBIT

➜ REMIND: BEFORE EACH RUN

• Check in the oscilloscope the VFATs are synchronous
• If NOT SYNCRONIZED we have to do a main reset
• Click ok ➜ until VFATs are in phase and trigger is on rising edge
• TDC cannot overwrite files: check you are incrementing the numbers on INFINITE RUNS (/home/XXX/XXXX/data /)

IComp Scan: HV scan run step by step

• START INFINITE RUN ON TDC
  • Filename: infinite #
  • Large number of events ～50000
• GO ON TURBO CTRL ➜ if program stops do STEP 1 in TURBO CTRL
  • VFAT Register-tab
  • Load VFAT Registers values from XML file
  • Choose file with right IComp values (HV SCAN IComp=XXX)➜Desktop/XXXXX/ConfigurationFiles
  • Now we have right IComp setting on VFAT
• THRESHOLD SCAN
  • Step THRESHOLD SCAN in TURBO CTRL
  • Save threshold in XML file
    • in Desktop/XXXXXXX/ConfigurationFiles copy one file and change name to corresponding run number
    • Open with Excel
    • Check IComp values
    • Select threshold where there are no hits
    • Threshold=vthreshold2-vthreshold1
    • Save XML (Developer-tab ➜XML➜Export)
• BEAM LATENCY SCAN
  • Check that TDC is running
  • Step BEAM LATENCY SCAN in TURBO CTRL
  • If counts are level for a VFAT you need to raise its threshold and restart latency scan
  • Export XML
  • Rename XML➜ [IComp,lat=Latency of VFAT1 on TURBO 1 (&2), th=threshold of TURBO 1 VFAT 1] ➜check/change these parameters in the filename * TDC
  • Stop the old run ➜ CTRL+C
  • Start a new run
  • Number of events 5000
  • Filename “TDC” [XML-filename]
• TURBO-DAQ
  • Load XML file
  • Check number of events (same as in TDC)
  • If “events in FIFO”< 90 ➜ increase delay in readout (“ Delay between Readout “=600, try 700)
  • If “events in FIFO”=90 all the time ➜ decrease delay in readout (“ Delay between Readout “=600, try 700)
  • Press ➜ to start
  • We can change delay while running ➜ Do changes between spills to avoid loosing events
