1 ALICE TPC Ne/CO2 Gas System

2 Mixing Rack

3 CO 2 -Removal & (O 2,H 2 O)- Cleaning Rack

4 Pumping and Storing Rack

5 Gas system Racks : Getting ready Individually PLC-controlled --> connect functionality

6 CO 2 - Purging Mode

7 Ne/CO 2 - Running Mode

8 User interface panels for ALICE TPC gas control system PVSS Prepared by IT/CO team under R.Barillere First panel prototypes are available

9 PVSS Pumping module PVSS Mixer module

10 Purifier module Purifier column sub-panel

11 TPC Gas Controls Milestones First versions of all necessary PLC modules available by the end of With this we can operate individual racks, test and hardware --> debug them… Full PVSS version by Q (dependant on UNICOS library updates) Full test of gas system + controls on test volume by Q2 2003

12 Connection: Gas System --> DCS Parameter list: (T, P) --> in, out, compressor, - cleaning, supply bottles, (O 2, H 2 O)--> in, out, Ne/CO 2 --> mixer V_drift--> Goofie

13 Goofie Drift Velocity Monitor 2 monitors In cave T_stabilized P = TPC Vdrift = in & out G G

14 Goofie Control Card: Preamplifiers shapers Digitizer : Altro - veccio Profibus Controller Applicom --> Labview --> Analysis

15 Goofie Control Status : Detector--> PT ready Card layout --> ready Mounting--> pending Plc-programming --> pending Labview Analysis--> On to do list DCS connection--> Go to to do list

16 Summary : TPC Gas System Hardware ready --> end 2002 Local Control--> end 2002 PVSS controlled--> mid 2003 PVSS - DCS--> end 2003 Goofie--> ???
