EPC Power Converters for ‘Master BIC Source RF’
• 3 central chopper quadrupoles critical for correct chopper action; now 3 individual user permits
10.11.11
BCC 6
EPC Power Converters for ‘Master BIC Linac4 Transfer (1)’
• All main bendings of transfer line; dependence on destination now through BIC truth table
10.11.11
BCC 7
EPC Power Converters for ‘BIC PSB OK (1)’
• For PSB injection beam permit need to combine individual ring user permits of power converters for BI.SMV and for BI.BSW

BCC 8
EPC Power Converters for ‘Master BIC PSB OK (2)’
• Status information of MPS, BE.BSW and BE.SMH
10.11.11
BCC 9
EPC Power Converters for ‘Master BIC PSB Ejection’
• Destination dependence through BIC truth table

Conclusions
• Modified BIS design will comply with EPC wish to avoid dealing with destinations at the power converter level.
• If the limit on the current acquisition is relaxed to a level where equipment damage can occur, the beam interlock system can obviously no longer guarantee equipment safety.
(concerns TL(1) BIC and PSB injection BIC)o A decision has then to be taken if the risk is considered acceptable
for example in combination with survey via software interlocks (SIS).
