  2. Interlocked Equipment • XTAX • XTDV To Access System • XTDX • DMPC INTERLOCKS Used to protect People and Equipment • Interlock System used in limitation of beam intensity • LOKN C.Beugnet

  3. Access if SAFE switch close and UNSAFE switch open BEAM ACCESS C.Beugnet

  4. DMPC Synoptic Diagram Only P04-XTAX0018 and P06-XTAX0052 are concerned C.Beugnet

  5. Protection is assumed when Equipment is in Dump position Information Web Info pages : http://cern.ch/sl-div-bi-ea/ >> Equip Info RUN<145>PIQ >> Info Test programs For XTDX (In/Out movement) example : T TDXMIO(1) >> 1 means Dump position = Safe For XTDV (In/Out movement) RUN<145>PIQ N/W >> Test >> Equip >> XTDV For XTAX, DMPC RUN<145>PIQ N >> Ctrl >> Equip >> Xtax >> Number RUN<147>NTAX.C (special DMPC) Top Piquet Diagnostic C.Beugnet

  6. Protect People around beam areas by limiting their intensity Declare the North Area SAFE or UNSAFE North Area is SAFE if all beams are SAFE North Area is UNSAFE if one beam is Not SAFE (cut SPS extraction) A Beam is SAFE if : Current in BENDS is limited (= beam energy limited) OR Elements on beam are in a position which limit its intensity (Tax, micro-collimator.....) A Beam is UNSAFE if its Intensity AND its Energy are not limited LOKN C.Beugnet

  7. LOKN Synoptic Diagram C.Beugnet

  8. Machines : Eanorth, PCA (SL/CO), Camac Vcc2117 (SL/BI) Power Supplies : Camac, Chassis LOCKN Modules : Input Gate Output register Master Unit Beam_Safe Equipment : Disconnected cables, Safe/Unsafe switches, mechanical problem Addressing Errors Possible Faults C.Beugnet
