Charge During this meeting the protection requirements for the first plasma will be discussed. Following input is required from OTHERS:

For each coil:

a) Max pulse current - CAPABILITY (What is the coil capable of, assuming proper cooling)

b) Time duration of the pulse - this is required to design the Pulse Duration & Period (PDP) device. Provide a window for each.

c) Rated continuous current CAPABILITY (What is the coil capable of, assuming proper cooling) for each coil

d) I^2*t CAPABILITY (What is the coil capable of, assuming proper cooling) of each coil

e) Proposed settings for over currents & I^2*t - SUGGEST 10% (is 5% OK?) ABOVE THE OPERATIONAL REQUIREMENT. What then is the factor of safety we have for each coil?

f) Other constraints in operation that will dictate relative coil currents based on mechanical forces etc.

g) PROVIDE INFORMATION OF OTHER INTERLOCK INPUTS e.g. CRYOSTAT TEMP. ETC.

Summary of Results

This was a peer review to discuss NCSX protection concepts. Many important points were discussed and a substantial number of chits were generated.

Disposition
