Recent developments in the Vacuum Control Software Far from an exhaustive list, we introduce to some recent developments for new device types, processes, functionalities through some examples deployed in LINAC4, NA62, HIE-ISOLDE, LHC and its injectors. The purpose is to have a first answer to the user question: “Oh, first time I see that in PVSS, what is it?”. May 08, 2015

??!! What is it??!!! Vacuum Control User https://edms.cern.ch/document/??????? May 08, 2015 2

H2 injection system in LINAC4 Close Dosing valve (preparation step) Injection Set Point defined by vacuum operator Normal mode of the Injection (Set Point defined by Source Control System) Source Set point directly send to dosing valve controller (very fast react mode) Dosing Valve Attention: Normally open Primary pump (operated by user in case of purging is requested) https://edms.cern.ch/document/1328204 May 08, 2015 3

Large Cryogenic Pumps Process is managed by the controller Remote control sends global orders and gets all the device statuses for animation and logging https://edms.cern.ch/document/1491552 May 08, 2015 4

Gauges with integrated Profibus interface Advantages : 1 Fieldbus cable for all the Gauges No Controller, limited Maintenance Low cost: 2/3 of money saved vs usual active gauges Remote control on the penning sensor https://edms.cern.ch/document/1491578 May 08, 2015 5

Input and Output Alarms (Hardware Alarms) Internal alarms and input alarms from external control systems Ex: Pressure Alarms for Sector Valves and Alarms from Access and fire detection control system https://edms.cern.ch/document/1491523 Device as a source for external control systems HW alarms Alarms generated by the PLC for external control systems Ex: Alarms send to NA62 detectors Ex: Alarm send to TE-ABT https://edms.cern.ch/document/1492253 May 08, 2015 6

Sublimation Pumps in PS Complex Remote control of the VPS controllers integrated in PVSS Degassing and Sublimation mode available Global machine process recipes https://edms.cern.ch/document/1505567 May 08, 2015 7

Search Device Comments and New Device List panel Search Device Comments: Produce the list of devices with any comments or with predefined comments(online or in the past) Device List for Vacuum Stand-by Piquet : Compare according to criteria current device states to references (save in the past) May 08, 2015 8

NEG pumps Synoptic: Control a Set of NEG pumps in a same vacuum sector (similar to Ion Pumps and Solenoids control) Default values for current, voltage and timeout in degasing and activation mode Manual mode with user set points (similar to Solenoids) https://edms.cern.ch/document/1491585 May 08, 2015 9

Thermocouples Synoptic: Purpose: Monitor vacuum vessel temperatures during operation https://edms.cern.ch/document/1491600 May 08, 2015 10

Beam Gas Vertex (BGV) Synoptic: Similar to BGI: Same Logic Layout slightly different https://edms.cern.ch/document/1505580 May 08, 2015 11

Cryogenic interlock for Sector Valves (LHC) Preventive Close of sector valves in case of superconductive magnet temperatures increase Preventive Close is disable in case of BEAM INFO (BEAM INFO = possible presence of Beam) - Deployed but not activated yet Sector Valve details panel: https://edms.cern.ch/document/1491591 May 08, 2015 12

HIE-ISOLDE Cryo Module Synoptic All Processes Off May 08, 2015 13

HIE-ISOLDE Cryo Module Synoptic Normal operation Turbo pump advanced diagnostic status: Rotation speed (%) Current (Amps) Real time monitoring of HW alarms send by TPG300 Pipe lines animation. May 08, 2015 14

And some reminders…. Manual or Auto mode: ‘M’: Manual (operator command) ‘ ‘: Auto (master process command) Valve: Software interlock status: ‘FI’: Full Interlock ‘SI’: Start/Open interlock ON/OFF label: ‘OFF’: Off/Close command ‘ON’: On/Open command Pump: https://edms.cern.ch/document/1328204&1373204 Courtesy: F.
