SLAC End Station A (ESA) Test Beam (ESTB)
The SLAC End Station A Test Beam (ESTB) was re-establishing in 2014 to take small fraction of SLAC LCLS beams into End Station test beam line. The operation is largely parasitic to the LCLS operations with electron beams in the 5-13 GeV range depending on the LCLS operation energy. From the FACET/ESTB portal, you can navigate to info on proposals, new user registrations, as well as ESTB schedules etc. The CALADIUM EUDET telescope owned by Carleton University has been installed at the end of ESTB as a precision tracking telescope with 6 planes of CMOS/MIMOSA sensors with ~3 micron spatial resolution. User Device Under Test (DUT) can be mounted on a movable stage in the middle of the telescope. For ATLAS pixel test beam users, a HSIO2/RCE based DUT readout will be provided as a standard readout utility.
Telescope operation
0. In ESA:
- Start chiller: 18 Celsius
- Switch on power supply: 8V constant --> check 2.0 A
- Switch on NI crate and TLU
1. Start sensors
- Remote access to NI crate:
-- Open Terminal
-- source access_NI_crate.sh
-- Login: telescope PWD: telescope+
- Start MI26.exe (upper icon on the Desktop)
-- Open .mcf threshold file, typically 6 (CALADIUM config files are in C:\opt\mimosas\config_files)
-- Press "Reset" --> 2.0 Amps
-- Press "All" --> 2.8 Amps
-- Press "Read" --> 2.8 Amps
-- Press "Start" --> check 3.6 Amps
2. Open Labview FPGA interface on NI crate, if not already open
- Double click MimosaDAQ (second upper icon on the Desktop)
3. Start EUDAQ on this machine:
- Open a second Terminal
- cd eudaq (points to /opt/install/eudaq/eudaq-1.5-dev)
- ./STARTRUN
- wait approx. 20 sec.
4. Open TLUproducer on NI crate
- Double click start_EUDAQ_tlu (fourth icon on the Desktop)
--> check in eudaq Run Control, that Produce TLU is connected
5. Configure EUDAQ
- select Config file
- Press Config
- wait till all green
6. Start Run
- Press Start (wait till all green)
--> check, that Trigger and Event Built numbers are increasing
--> check OnlineMonitor, and reset (upper left x-button)
7. Stop
- Re-configure (5.) and Re-Run (6.)
OR
- Terminate and press "Reset" in MI26.exe at NI crate to stop sensors --> check 2.0
