CMS Pixel Workshop
• Overview of Pixel Control System • Status of US-based work• Incorporation into prod. & system testing • What is next

What exists now?
• “Cosmo” (vers.1.6.9c) for pulsing, LED, 90Sr: PSI43 – 1st version about 1 year ago– Now 10 versions later– Written in C, Tcl– I/O via PC parallel port to a “FEC” & FPGA TBM– Server communication limits to 30 Hz rate
• “Run Control” GUI + Cosmo for Testbeam – DAQ integrated to Si Strip telescope– Currently In use at FNAL Testbeam– Now for PSI43– PSI46 ready in ~1month

• Cosmo changes: PSI 43 46– Hardware– New DAC specifications– Pixels: 150x150 (2756) 100x150 (4160)– Scripting and rate improvements– Should be ready in 1 month
• Production Testing– Initial Plaquette test (module)– 3 day burn-in (32 modules)– Blade– Full disk
• System tests: using AOH, FED, FEC, TTC
Needed Soon

Near Term Plan
• At FNAL: get Linux PCs– Install PVSS and XDAC
• Try simple monitoring• Use XDAC process control
– Install DB– ORCASummer ’04
• Modify analysis and control software – Production testing– System testing– Integrate DB coupling– ORCA?
slide 17
Conclusions
• Software exists to control modules of PSI43.• PSI 43 control software used for bench and testbeam.• Modifications underway to achieve PSI46 readout.
• Structure exists to evolve into production testing.• Incorporate more of the CMS environment to get to final runtime system.
