Partial upgrade, keeping some VME SCLabs Adriaan Rijllart11 Ethernet DVMs Operator Console Quench DAQ Magnetic Measurement ADCs VME Integrators

Reasons to adopt PXI Industry standard for instrumentation, based on PCI Supported by 60 vendors, commercialising >1000 modules PXI is 10 years old Smaller, cheaper than VME Key hardware features: triggering and synchronisation, shielding, speed (PXI-express, follows PCI express development) Key software features by National Instruments: LabVIEW, LabVIEW Real Time, integrated network communication, drivers Key OS features: Pharlap, VX-Works, Windows, Linux Connects to VME, which allows partial migration, keeping VME investment where needed SCLabs Adriaan Rijllart12

Maintaining present systems Step 1: Replace Sun with PXI, keep MXI-VME Advantages: Up to date LabVIEW version Up to date OS (no Solaris) Disadvantage: VME processors, modules and crates are kept (some are obsolete) SCLabs Adriaan Rijllart13

Upgrade plan Step 2: Replace VME with PXI More compact, higher density modules 3 VME crates with 56 modules Replace 5 VME ADC with 1 PXI ADC Higher performance ADCs Higher precision, up to 24 bit ADCs and 7 ½ digits DVMs Faster acquisition, if needed Maintenance advantages: No SBS, BAB, VME, MXI Disadvantage: higher cost SCLabs Adriaan Rijllart14

Replacement of all Sun based systems All Sun based measurement systems will need to be replaced (B180 Magnet Rescue Facility, B181, B867, …) Not part of the SC laboratory review, but to be kept in mind My inventory has 90 Sun workstations SCLabs Adriaan Rijllart16

Recommendation Plan 1: maintenance. Replace all Sun measurement stations with PXI processors, keeping the VME crates and modules. Plan 2: upgrade. Develop one pilot DAQ system in PXI for validation. Replace all DAQ systems with PXI system. B163 Plan 1: maintenance, replace Sun workstations. Plan 2: replace DVMs with PXI if needed for higher speed. B165 Can be maintained as is (no Sun workstations) For new measurement systems PXI should be considered. SCLabs Adriaan Rijllart17
