ECS CALO HV Control

ECS CALO HV Control • Outline • Status of the calorimeter ECS HV control. • ECS LV and MV control. • Planning CALO ECS meeting 5.11.08 Anatoli Konoplyannikov /ITEP/

ECS CALO HV Control • The ECS CALO HV control projects have been developed in close contact with the LHCb Online group. There are two type of the projects. One is for ECAL/HCAL and second for PS/SPD. In total six calorimeter HV projects are running on the Online PC’s. • Each project allows: • Work within the LHCb FSM hierarchy. • Set HV for individual PMT or a group of PMTs; • Set HV for all detector channels with a desirable ramp time factor; • Perform a fast emergency HV OFF; • Monitor : • HV control signals, and produce the warnings in case if the set and read values are different more than 1%; • status of the 100 V and LV power supplies for group of PMT’s, and produce the errors if values are out of the limits; • There are many possibilities to create the recipes and there is a connection to CALO specific database. • The standard recipes for PHYSICS and COSMICS runs have been prepared.

ECS CALO HV Control HARDWARE 40 HV_LED_DAC boards control a high voltage of about 7500 CW bases of the ECAL and HCAL sub-detectors. 2 HV crates produce the high voltages for 200 MAPMT’s of the PS and SPD sub-detectors. Hardware interface to the ECS is Specs mezzanine ECAL/HCAL HV_LED_DAC board and PS/SPD HV crate. CALO ECS meeting 5.11.08 Anatoli Konoplyannikov /ITEP/

ECS CALO HV Control • There are three layers of the panels in the developed HV projects with dedicated functional meaning: • Top level CALO HV panel shows a summary status of the HV and LV-MV power supplies powering the HV electronics of the calorimeter sub-detectors. From this panel one can control HV using standard FSM way. The panel is dedicated to the shift and CALO piquet operators. • Top level sub-detector HV panel shows a power supply summary status, but mainly dedicated to manage the recipe creating and editing. Procedure of the recipe creation is very flexible. There are three possibility to create the HV recipe: • Load from a file; • Load from internal CALO DB; • Prepare recipe using the expert panels; • In the same time the panel includes a tool for the recipe values scaling. • The panel is dedicated to the CALO piquet operators and experts. • III. Low level panels are dedicated mainly to an expert operation and allow to control HV on the specific hardware groups, an individual channel and tune different monitoring parameters. (warning thresholds of the power supplies voltages, HV ramp-time coefficient, relay delay time ...) CALO ECS meeting 5.11.08 Anatoli Konoplyannikov /ITEP/

ECS CALO LV and MV Control HARDWARE There are six MARATON LV power supplies boxes for feeding the calorimeter High Voltage, VFE and LED monitoring electronics. The standard PVSS software based on JCOB fwWiener and LHCb online group lbLV components is used for a control these devices. The name of the project is CADCSLV. • Four Agilent power supplies placed in barrack D3 are used for producing middle voltages for calorimeter sub-detectors. • a) Two ECAL/HCAL four units crates (100V, 30V,100V, 30V for A and C sides); • b) Two PS/SPD one unit crates (150V for per side); • The PVSS software for control and monitor these devices was developed. The soft is installed on the CADCSC01W PC and the project name is CADCSMV. • Agilent DIM server was written and four Agilent DIM servers are running on this PC (launched automatically from Service+). • Control PVSS software is based on JCOB fwWiener and LHCb online group lbLV components. • Each power supply has one LAN connection to ECS. • During last months these PVSS projects have been tested. They are stable and now in production stage. Photo of the MARATON power box Photo of four Agilent MV power supplies CALO ECS meeting 5.11.08 Anatoli Konoplyannikov /ITEP/

ECS CALO HV Control • Planning • Improve projects stability. • Test HV systems with different recipes and study procedure of the warning and error handling. May be some action (let say changing the HV from READY to STANDBY1 state) will be performed automatically in case of some warnings. • Add a user friendly tool for a channel masking. • Improve the panel informative content by adding the tool tips and help panels.
