Testbeam July 2010

Shifter instructions

If you have any questions on the run plan or these instructions, ask Alessandro or Jens. If it can wait until morning, that will be appreciated.

Start of shift checklist

1. Ask the previous shifter, check their elog entry and the run plan table to see what you will have to do during your shift.
2. Create a new entry in the e-log by duplicating the shift-log template here and here (outside CERN). Click on the "Duplicate" button at the top. Change the author field and the subject to reflect your shift. Update the tables during your shift and be sure to record all actions taken with time stamps. If experts are working with you and you don't understand the actions being taken, either ask them to tell you or ask them to help you update the e-log.
3. Check the temperatures, bias voltages and currents of the DUTs and note the values in your elog entry.
4. Check hitmaps and correlation plots during the runs to make sure the beam hits the DUTs. If the position of the beam wrt the DUT changes, cross check with MicroMEGAS people if they changed anything (shouldn't happen!).
5. While taking data make sure that the book keeping is complete. See section below.

Bookkeeping

• Fill in the EUDET spreadsheet and mark runs green or red (good/not good for analysis)
• Note all accesses and changes to the setup, including config files, in the EUDET spreadsheet and in the PPS elog
• Update the runplan table on this twiki page

To access the PPS elog from inside the CERN network, follow this link.
If you are not in the CERN network you will have to set up an ssh-tunnel through lxplus: $ ssh -L8080:mpnoatlas01.cern.ch:8080 username@lxplusSPAMNOT.cern.ch
Now you can reach the elog from <http://localhost:8080/PPSLog/>.
To access the EUDET spreadsheet you need a google mail account. Send an email to Jens, giving your google mail adress, to get access.
In the counting room, if you don't have your own gmail account, you can access the spreadsheet here, using the account eudet.unige@gmailSPAMNOT.com pwd: gsigsigsi

End-of-access checklist

1. If the telescope was touched (even the frame) note that clearly in the elog and the spreadsheet!
2. If the setup was physically changed, DUTs changed or moved from their previous position, create a new GeoID in the EUDET run control, note changes in elog and spreadsheet, and take an alignment run.

Explanation:

• FE Adress: This is the geographical adress of the FE. It has to be unique within one batch of FE operated at the same time. GA 8 is reserved for the reference DUT.
• Position: This is the position of the DUT counting downstream. I.e. position 1 is furthest upstream, position 8 is the furthest possible downstream, if we use the Dortmund box with four slots.
• Batch: Due to the large number of DUTs we will probably have to swap DUTs at some point during the testbeam. I will try to put the high-priority samples in batch 1.

Hardware

HV/LV

We will mostly use the shared testbeam setup at CERN, including LV and HV power supplies in the CAEN crate. The CAEN power supply can be operated via a terminal application on EUDETMAC001.cern.ch. To access it, open a terminal and telnet 129.194.55.200:1527. Press enter to get the login into the CAEN1527, you have to login as "admin"; guess the password. In the "main" menu, choose "channels" to get the overview. You can change the voltages, names of the channels and on/off by going there with the cursor and pressing space or entering a new number/designation.
Dortmund agreed to bring one ISEG HV power supply. This has been placed in the H6B control room. The two channels are labelled "Iseg 1" and "Iseg 2", the HV is transferred by two SHV cables labelled "APIX A" and "APIX B". Currently, the pairing is "Iseg 1 -> APIX A -> First DOBOX-sample" and "Iseg 2 -> APIX B -> Second DOBOX-sample".

Beam finder

Branislav "Bane" Ristic built a combination of two scintillator strips with SiPM/MPPC readout which can be used to quickly scan a large area to find the beam (e.g. if the beam optics were modified and the beam is wide and fuzzy). It is currently mounted to the DOBOX-table downstream of the DOBOX. The SiPMs HV is supplied by the CAEN crate, the channels are labelled MPPC1.1, MPPC1.2, MPPC3.1 and MPPC3.2 (this one is broken). The usual voltages are 69.8, 69.8, 70.4 and 70.55V respectively usual currents drawn are on the order of few uA. In the H6B control room, there are two counters and a timer to look at the event/trigger rates per spill. Usual dark count rates are below ~Hz, usual spill counts are some 10^4 to 10^5 per spill. The idea is to move the beam finder from the lower left corner to the upper right corner of the search region in 5mm steps and find the position of maximum counts/spill. This can be quite fast if operated by two people (one writing down the numbers and one moving the table in 5mm steps). A documentation leaflet by Bane can be found here.

Temperature logging

Several of the irradiated samples have PT1000 temperature sensors attached to them. Those sensors are connected by a flat ribbon cable to the so-called PT-NUT, which is a small box positioned below the DOBOX in the testbeam area. The PT-NUT itself is connected to the internal ethernet based network system and listens at the ip 192.194.55.93. The readout and logging is realised with a stand alone program running on the small IBM T40 notebook. The notebook is designated "turtle" and lies in the most-left rack below the ISEG power supply. Please note that the battery is nearly spent and therefore an uninterrupted wired power supply is necessary. In case your have to reboot the notebook, please use the following credentials for login:

user: eudet

password: APIXrules!

In order to open a console please click on the little black rectangle icon which can be found on the desktop. Then type the following two lines, each finished by pressing enter:

cd /sw/temperature_monitoring_system/src/

./temperature_monitoring_system 192.194.55.93

You will see see that every few seconds the a new line is scrolled up, showing the temperatures of the sensors. At the same time those values are written into a text file which is localised in the same directory as the binary. When the program is restarted, a new file is automatically created, adding a time and date stamp to the file name. Please do not close the terminal window as that will cause the program to terminate and stop logging. You can resize it so that both the temperature display and hv display fit on the same screen.

hv logging

The caen power supply has a voltage limit of 500V for its hv channels. Currently those channels can (and should) be only monitored by hand. For two DUTs a higher voltage (up to 5kv) can be provided by the iseg power supply which is stationed in the control room and connected to the testbeam area by two long shv cables. This iseg is connected through an agilent interface to the internal ethernet based network system and listens at the ip 192.194.55.97. The readout and logging is realised with a stand alone program running on the small IBM T40 notebook. The notebook is designated "turtle" and lies in the most-left rack below the ISEG power supply. Please note that the battery is nearly spent and therefore an uninterrupted wired power supply is necessary. In case your have to reboot the notebook, please use the following credentials for login:

user: eudet

password: APIXrules!

In order to open a console please click on the little black rectangle icon which can be found on the desktop. Then type the following two lines, each finished by pressing enter:

cd /sw/hv_monitoring_system/src/

./hv_monitoring_system 192.194.55.97

You will see see that every few seconds a new line is scrolled up, showing the voltage and current of both HV channels of the ISEG. At the same time those values are written into a text file which is localised in the same directory as the binary. When the program is restarted, a new file is automatically created, adding a time and date stamp to the file name. Please do not close the terminal window as that will cause the program to terminate and stop logging. You can resize it so that both the temperature display and hv display fit on the same screen.

TurboDAQ-problems

In case TurboDAQ crashed, try to run the Resource Manager "Resman" before you restart TurboDAQ. If this also does not help, restart the Computer (user: eudaq, PW: APIXrules!) and good luck!
