- For example, IN5 at ILL, NEAT at HMI, DCS at NIST.
- Same type of chopper spetctrometers at pulsed neutron sorces are also planned for SNS (CNCS) and ISIS 2nd Target Station (LET).
- Very recently, we have succeeded in running our proto-type fast disk-chopper at the speed of 300 Hz. Although still we have many issues to overcome in developing our chopper, we have good hope to complete it.
