For CW beam and macropulses: ADS, SNS, HPPA

l
  • Beam repetition frequency 60~500 MHz
  • Average current with 1 µA resolution
  • Fast beam loss interlock 1 µs
  • Linearity error <1.5%
  • Beam loss resolution <1 %
  • Output voltage full scale (in 1 MΩ) -4 V … +4 V


Independent of bunch shape and width EMI, RFI, field and temperature immune.

Operating principle.

The CWCT is a current transformer with strict limits on lower and upper cut-off frequencies, tailored to the beam RF. Its lower cut-off assures negligible droop between bunches. Yet, droop is high enough to allow fast differentiation. Its upper cutoff is high enough to allow output signal return to baseline after each bunch, yet low enough to assure an output duty factor close to 50%. Thus it is tailored to the bunch length, allowing the measurement of short bunches. The BCM-CW-E is the electronics module processing the CWCT output signal. By applying fast sample-and-hold techniques it measures the average beam current with microsecond response time. Properly adjusted signal amplification and filtering improves the resolution of small beam current fluctuations*.
