MERIT

beam line
Beam line
  • No modifications to TT2 line
  • FTN beam line
    • Displacement/installation of quadrupoles downstream of shielding
    • Causes possible power cable installation to bat. 263
      • Not urgent, can be down in shutdown 06/07
  • Cut/stop TT2/FTN vacuum at shielding
    • install beam window just downstream of shielding.

the merit cycle

and repeat

B-field

Solenoid temperature

Proton intensity

The MERIT cycle

The solenoid is operating at 80 K. A power ramping takes place about every 30 minutes.

  • Repetition rate is limited by the cooling process of the solenoid.
    • A few seconds B-field ramping
    • 20++ minutes for cooling procedure

n2 exhaust
N2 exhaust
  • Principle of operation agreed with SC/RP and SC/GS
    • Release of 200 liters LN2/ 30 minutes at ambient temperature
      • 1400 m3 N2 gas/hour to a total ventilation of 27000 m3/hour
      • EDMS 700153
    • Including activated LN2 of up to 1 liter/beam cycle
      • Delayed release by >2 minutes after beam to reduce short-lived isotopes
      • EDMS 700178 and 697857
  • Currently installation of exhaust line in TT10 and TT2
    • Layout agreed on with A. Spinks, N. Gilbert, G. Robin, C. Lacroix
    • Completed before TT2 closure at end of February
  • Operation of LN2/N2 system starts in late autumn 2006
  • Impact on TT10 operation
    • Portable ODH monitoring required
    • Definition and signalization of areas concerned to be finalized
    • MERIT alarm from TT10 ventilation and radiation monitors to be installed

power supply power line
Power supply, power line
  • Transformer/Converter installed at bat. 193
    • Refurbishment during spring 2006
  • AC cabling (18kV to transformer to converter)
    • Building 193 only
    • Will be done in autumn 2006; AD shutdown
  • DC
    • Currently ongoing
    • Completed before 24th February (TT2 closure)
  • Safety coordinator
