Strip Status

Status bits are failure states, i.e. status of 0 is good, anything else is bad. Strip status bits are defined as

How to access database:

See Renee's instructions how to create and upload pedestals/status attached
-----------------

I had hoped to write this tutoral once all code was in CVS and I had automated all of the loading and writing scripts. Unfortunately these conditions are only partially fullfilled at this time, so this procedure describes how to make pedestal and status files needed to load to the database:

• mkdir FgtPed
• cd FgtPed
• stardev
• cvs co StRoot/StFgtPool/StFgtRawDaqReader
• cvs co StRoot/StFgtPool/StFgtCosmicTestStandGeom
• cvs co StRoot/StFgtPool/StFgtPedMaker
• cvs co StRoot/StFgtPool/StFgtStatusMaker
• cvs co StRoot/StFgtPool/StFgtQaMakers
• cons
• cvs co StRoot/StFgtPool/StFgtQaMakers/macro/makeFgtPedAndStat.C

You will need to open makeFgtPedAndStat.C and set the database time manually (next step is to automate this).  This timestamp is used to get the correct mapping:

• dbMkr->SetDateTime(20121108,000000);

You also need to set the file and output file name fields at the top, but this is easily done dynamically if you wish.  Next simply run the macro :  root4star -b -q makeFgtPedAndStat.C.  Eight files will be part of the output:

• Filename.FGT-ped-DB.dat
• Filename.FGT-ped-stat-info.txt
• Filename.FGT-ped-stat.pdf
• Filename.FGT-ped-stat.ps
• Filename.FGT-ped-stat.root
• Filename.FGT-ped-stat.txt
• Filename.FGT-stat-DB.dat
• fgtMapDump.csv

The .dat files need to be loaded to the database using the macros

• cvs co StRoot/StFgtUtil/database/macros/write_fgt_pedestal.C
• cvs co StRoot/StFgtUtil/database/macros/write_fgt_status.C
• cvs co StRoot/StFgtUtil/database/macros/fgtPedestal.h
• cvs co StRoot/StFgtUtil/database/macros/fgtStatus.h

Now you need to open each of these macros and set the database time and file input correctly before running via the standard root4star -b -q write_fgt_pedestal.C.

Software for computing (making), reading (from file or DB) and plotting pedistals has been written.  The DB functionality is not fully implemented as of Jan 10, 2012.

At the moment FGTEventDisplay incorporates much of the code that we've been using to generate plots, and allows the viewing of individual events.

The online software uses the 'JPlot' framework:

Planned Measurements

 

For each of these measurements we should have a plan/protocoll what we want to do (conditions, time, software...)

 

These are the official drawings and documentation used for fabrication of the FGT Front End Electronics hardware. We will try to maintain this page up-to-date with any revisions.

Planning the Beamtest at DESY

 

This is a short overview of the front end and readout electronics of the FGT. The emphasis is on providing some documentation on all the components.
