2. OUTLINE  System Basics - Recall Software and Hardware components HV Control Structure  HBD HV Control – Introduction Getting Started Features  Relay Board and Trip Detector  Coming Up Upgrades For Run9 | PHENIX, BNL HBD HV Control System HBD Meeting :: September 30 th, 2008 HBD HV Control & Monitoring System Manuel Proissl Page 1 of 13

3. HV SYSTEM BASICS  HV Control is based on CS architecture (before: TS)  System communicates ONLY with own HBD Server on va022  HBD server (/hbd/startHBD) sends CMDs and receives data from hvclient  robust and secure!  Two Modes: SA1 and HBD Expert  Two User / Access Levels: STANDARD and SUPERUSER  3-Layer System has been used:  40 channels to serve (20 GEMs, 20 Meshs)  Hardware: L1458HP mainframe, L1471Ns, Voltage Divider, Relay Boards  HV Control is INDEPENDENT of Relay Board Installation!

BNL Username Indicating if code is correct, wrong or unknown. THE PROTECTION SYSTEM – General Introduction –  Running Shift Mode means only ONE client at a time can login to HV Control, which is the specially authorized system in the counting room!  Activation code indicates user level: STANDARD or SUPERUSER  System in counting room has superuser privileges, meaning nobody else can login; however, HBD experts can take over control at any time (notification for SA1..)  System NOT responding, superuser ID set free automatically  Use of Shift Mode outside of BNL prohibited by firewall  Expert Mode: no network restrictions!

13. RELAY BOARD AND TRIP DETECTOR  System has been used so far and hasn’t shown any issues, until now….  Indefinable problems occurred:  Having just the connection cable to trip detector hooked up, a “virtual trip” can be seen, meaning the LED on the board indicates trip, however, after measuring it shows still same op. voltage.  Having the relay board and L1471N SHVs and connection cable hooked up (operating case), we see one relay trip causing multiple random LeCroy channel trips.  Even switching from the non-isolated RS485 to the isolated port didn’t help!  Powering the board independently from mainframe didn’t help!  Possible explanation: airborne NOISE sparks Shielding Test: taking the relay board out of the mainframe, shielding the LeCroy module all around seemed to solve the issue – problem almost disappeared  Next step: placing all 6 L1471Ns on right, relay boards on left side of mainframe and strong isolation in between… if this brings us back on track, we can use the relay board for Run9.

14. COMING UP  Relay Board research will continue, but is independent from HV Control development!  Real-time simulation of all 40 channels (GEM and Mesh)  Major server software work necessary – making parameter settings via software possible and secure (file system not exposed!) Additional live-login to hvconfig without opening another tunnel Getting va022 ready for Run9 – auto-starts, hvclient, etc. (with Martin)  Switching from table to database (to design) for parameter setting  Online documentation and Introduction Tutorials (HBD website) Upgrades For Run9 | PHENIX, BNL HBD HV Control System HBD Meeting :: September 30 th, 2008 HBD HV Control & Monitoring System Manuel Proissl Page 13 of 13
