Rad test facilities
• SEU (Single event upset): (Proton)
– TSL proton beam at Uppsala in Sweden which has a
diameter of 15 to 20cm
• NIEL (Non Ionising Energy Loss) : (neutron)
– PROSPERO nuclear reactor at Valduc near Dijon in
France which produces neutrons at 1Mev energy
• TID (Total Ionising dose): (Gamma)
– cobalt 60 source in Cassacia in Italy near rome
• ….
CAEN: Can bus test over 520m
need to add those bias
resistors, to improve
noise margin
CAN bus collision error
A sends
=A transmitted data
=A received data
B sends
=B end cable signal
Example of collision.
B end is transmitting, then A suddenly starts transmitting as well (upper trace) =>
collision and broken communciation.
Conclusions on communication cable test
• With CAEN’s implementation, of 250kbaud, timing
violations are detected : Need either 125kbaud or modify
timing of can bus = modification can only be done by
CAEN (20k€)
• Cable bandwidth SCEM 04.21.52.xxx.x allows 1Mbaud
• Clock transmission has been tested to work with a duty
cycle distortion of <10% at 1MHz
• This family of cables would support the CAN bus
communication at 125kBaud over 500m using the standard
CAN aribtration and protocol.
• EASY3000 crate may catch fire!
Status Sep. 2007
• CAEN solution is at the most advanced state:
• Will fit into the tunnel in 3(4) crates includes:
–
–
–
–
Temperature monitor
Quartic/Gastof supplies (=1 crate)
Very few long cables: Power 400V+communication+48V
May need 400V noise filter A3000NF (ask Detlef for <200W).
This module has not been rad. tested but its an entirely passive
components. Could be outside of tunnel!
• Wiener supply solution:
– LV in tunnel. HV in Counting room. But also a all-in-tunnel
version
– Temperature in counting room
• HV 100V(ok?) module A3501 has not been radition tested.
Equivalent to A3540 (12x4KV) which is approved for
Atlas
Conclusion on power supplies
• Both CAEN and Wiener are still candidates
• Wiener and CAEN need radiation tests
• CAEN need customization on
communication
• Wiener need customization on HV in their
all-in-tunnel solution
Actions
• Specify radiation requirements and test protocol for Wiener
(and for CAEN)
• Find locations for above radiation qualification tests for
Wiener and for CAEN
• Radiation test CAEN HV 3501(Si bias) and A3006 (4-16V
Gastof /Quartic)
