ION PUMP HVFT / Connectors Varian StarCell Solution (no longer commercially offered as standard) Gamma Vacuum SAFE-CONN Solution ION PUMP HVFT • • • • • Gamma Vacuum HVFT Compact, protected HVFT Commercially available Reliable Connection Verification Safety • • • • • • Varian StarCell HVFT Known Corrosion problems Corrosion problems at SLAC Dan Wright has a stack of failed HVFTs in his office SLAC tried gold coating to solve corrosion problem – unsuccessful Leverage on connector applies to HVFT ceramic – breaks ceramic. No longer commercially offered as standard High Voltage Safety SAFECONN Safety Interlocking • Separate isolated interlock cable controls high voltage power • Eliminates exposed high voltage lead - Safety • Eliminates false vacuum readings when cable is not connected to pump – Connection Verification • Bakeable & radiation resistant SAFE-CONN HV Cables • Standard HV Cables • • • • • 380046 380047 380048 380053 380091 3m 6m 10m 30m 100m • Other lengths and custom cables available TM DIGITEL Controllers DIGITEL MPC DIGITELTM SPC Multiple Pump Controller Small Pump Controller • • • • • TM • • • • Up to Two Independent High Voltage Supplies Up to 4 HV connectors 500 or 100 mA Transformer Design 8 Standard Setpoints TSP/NEG/ Bake Control Capability Single High Voltage Supplies 15 mA Switching Design Single Standard Setpoint 2U, 1/3 Rack Packaging System Protection Starting Protection - AutoStart • Ensures pump is properly started by calculating acceptable watts over starting period for specific pump • Automatic shutdown if pump is not operating correctly • Three Auto-restart attempts without user intervention Running Protection - AutoRun • Continuous wattage monitoring for specific pump • Low voltage cutoff for short and high current conditions System Automation • AutoStart/AutoRun • Automatic switch over from starting to running parameters based on monitoring and pump size • Vacuum Loss Monitoring once operational • Auto-Power Recovery (Because of AutoStart/AutoRun) • Can be configured to initiate HV after power loss (maintain Vacuum) • Standard Computer Interface • All features are available for inquiry and control • RS232/422/485 • Eight Setpoints standard (4:TTL, 4:Relay) • TSP Automation capability (with Remote TSP Controller) DIGITEL MPC Reliability • Transformer Design • Transformer based power supplies radiate less electrical noise and require less shielding than switching supplies. Switching supplies rely on high frequency capacitor charging to amplify the voltage, creating noise, possibly interference. • Quality Manufacturing & Design • Good, reliable HV designs are difficult, building a switching power supply increases difficulty and takes many more components (10X a transformer HV section). With more components the reliability is reduced. • Field Tested Operation DIGITEL MPC Part Numbers • MPC-1-US220-232-N-N • Supply 1: 500-Pos-7KV-K4 • Supply 2: None This is DIGITEL MPC with: 1) 1, 500mA HV section 2) 220V input voltage 3) Rs 232 communications (485 configurable) 4) No HV Enable option -N 5) No TSP Option -N 6) 4 SHV-10 HV outputs DIGITEL MPC Part Numbers • MPC-2-US220-232-N-N • Supply 1: 500-Pos-7KV-K1 • Supply 2: 500-Pos-7KV-K1 This is DIGITEL MPC with: 1) 2, 500mA HV sections 2) 220V input voltage 3) Rs 232 communications (485 configurable) 4) No HV Enable option -N 5) No TSP Option -N 6) 2 SHV-10 HV outputs (1 for each HV section) DIGITEL MPC Part Numbers • MPC-2-US220-232-N-N • Supply 1: 500-Pos-7KV-K2 • Supply 2: 500-Pos-7KV-K2 This is DIGITEL MPC with: 1) 2, 500mA HV sections 2) 220V input voltage 3) Rs 232 communications (485 configurable) 4) No HV Enable option -N 5) No TSP Option -N 6) 4 SHV-10 HV outputs (2 for each HV section) SAFE-CONN 5V isolated transformer SAFE-CONN Board SAFE-CONN 1 SAFE-CONN 2 CPU Board Optical Isolation HV 1 HV 2 HV1 to Pump 1 HV2 to Pump 2 SAFE-CONN DIGITEL MPC Chassis SAFE-CONN Isolated +5V HV1 SAFE-CONN Interlock SMB Connector SAFE-CONN Connection HV1 @ Pump 1 HV 1 HV1 to Pump 1 SHV-10 Connector SAFE-CONN Isolated +5V HV2 SAFE-CONN Interlock SMB Connector SHV-10 Connector SAFE-CONN Connection HV2 @ Pump 2 HV 2 HV2 to Pump 2 SHV-10 Connector SHV-10 Connector SAFE-CONN DIGITEL MPC Chassis SAFE-CONN Isolated +5V HV1 SAFE-CONN Interlock SAFE-CONN Connection HV1 @ Pump 1 SMB Connector HV 1 HV1 to Pump 1 SHV-10 Connector “K1” SHV-10 Connector HV1 to Pump 2 SHV-10 Connector “K2” SHV-10 Connector SAFE-CONN Isolated +5V HV1 SAFE-CONN Interlock SMB Connector SAFE-CONN Connection HV1 @ Pump 2 SAFE-CONN • SAFE-CONN is a parallel, isolated 5 volt circuit that enables / disables HV. The connection order (Ground, HV pin, then HV enable) and dis-connection order (HV enable, HV pin, then ground) is important in the design. The +5V is isolated to eliminate interference of HV transients and HV shorting to the SAFE-CONN circuitry.
