2 Software tool for doing XCAL LED timing scan and data analysis Procedure: Anatoli Konoplyannikov I. Collect LED timing scan data from sub-detector top level panel. For doing this one has to do: a)select activity “PHYSICS|TimeScan”; b)configure XCAL DAQ partition with DEFAULT recipe; c)set number of steps to 26 and events per step 800, TAE = II. Using standard CALO scripts create the root file with the name RunNumber.root (description on Olivier’s TWiki pages), then create a new directory xcRunNumber on disk S:\everyone\akonDATA and put the root file into this directory (where x is e or h). III. All analysis codes are on S:\everyone\akonDATA\anaLED10\xcal. There are two type of the root codes one is xc_fstTAE5.c for first step of the analysis. In this time a detailed file with the histogram parameters on each detector cell for five TAE is created per each step. For visualization the signal curves and creating the LEDTSB recipe file, the xcA_secana_t0Show.c or xcC_secana_t0Show.c code is used (individual code per side of the sub-detector). Analysis steps: 1.edit root code file for defining correct Run Number (two lines); 2.launch ROOT on lynux online PC and execute code: root.x xc_fstTAE5.c 3.then execute code: root.x xcX_secana_t0Show.c 4.The output JPEG files with signal curves and text RECIPE file will be created.

4 Results of the XCAL LED timing scan and data analysis CALO meeting Anatoli Konoplyannikov [ITEP] The signal curves for all FE and PIN channels are produced as analysis output. As example a faulty channel diagnostic with ECAL LED system is shown below: Typical shapes with one faulty operated channel. PIN diodes signal shapes as seen by dedicated FE board.

6 Answer on typical questions How To: CALO LEDTSB tuning and ECS control Anatoli Konoplyannikov Q. What to do in case if LED signal appears in Prev1 time slot in ~80% of cases; in 20% of cases it is in T0, there is also some small amount of hits in Next1 time slot? A. 1. as you know, LEDTSB is implemented on Delay Chip developed at LAL. Due to this reason it has the same behavior as for FE boards (see Frederic’s presentations). It has some unstable region of delay settings (1 - 2 ns) for each of 25 ns interval. For solving un-stability problem one has to change the delay settings for these channels by one ns, collect data and see what is changed. For doing this: 2. launch the ECDAQX1 DEN, open by “view” the LEDTSB devices, select needed board / channel and change a delay value in "Delay" column. Afterwards push "Apply" button, collect data and check the event numbers in prev, T0 and next samples. 3. if a new settings is OK, update the DEFAULT recipe from top level LEDTSB panel.

7 How To: CALO HV power supply and ECS control Anatoli Konoplyannikov Q. What to do in case the problems with the HV system restarting? A.As was written in CALO HV tutorial, after rebooting PC and restarting a HV project, in case of the problem, one has to do: 1. go through the main First Time initialization panel (one per each side of sub-detector) and perform Specs_Init and Set_HV_OFF actions (wait while operation is finished) and then close the panel. 2. check the logout of a HV project (the panel could be opened from Project Administrator panel). In case of normal running one can see the HVmonitoring script messages. If there is no any messages, one must restart the HVmonitoring script.

8 How To: CALO LV - MV power supplies and ECS control Anatoli Konoplyannikov Q. What to do in case if the MV power supply is in an unexpected OFF state? A. 1. one has to take a corresponded HV project and set HV off for both sides 2. using the Service+ restart CADCSMV project (stop -> start); 3. from DCS partition set corresponded MV voltages ON; 4. using HV projects set needed HV and release HV projects. Q. How initialize the Agilent power supply after a current overload? A.1. Set all HV OFF for problematic sub-detector using HV projects; 2. Using DEN of the CADDCSMV project go to hardware and open problematic power supply; 3. Push “Power On” for reinitializing Agilent PS. After this all voltages will be at zero. 2 3
