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!

USER INTRO – GETTING STARTED

With HBD installation on December 1st, 2008 – the installer will become available for download from va022> /hbd/hvcontrol/hbdcontrol.exe Easy access through HBD website

Follow installation steps…. BNL Life No. and Serial required! After Reboot and Click on Desktop Icon:


Splash

Initializing interface… Checking network connection and speed First-time user??

System Activation Login: SA1 or Expert

YES NO



HV System Activation is required for first-time users! You need… Locate Public Key on local disk Corresponding username

– same as to RSSH machines

16-digit activation code Unique code defining privileges Provided to every HBD group member

and one for shift crew (pre-inst.)

By clicking “Verify” - the system checks

in hvdb the code’s existence and

displays BNL ID and Name for

user verification of correct code pick-up By clicking “Activate System” – loads

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!



If your user access level, based on code, restricts you from running Expert Mode, a error window pops up – denying access!

BNL ID and password only have to be set once by simply saving the settings

No access restrictions to Shift Mode

Troubleshooting, Q/A’s under “Help”

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.



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
