Press Release Summary:
Able to measure pulse currents up to 50,000 A, CM-1-E-beam current transformer combines 10 nanosecond risetime and 10 mV/A output sensitivity. It is constructed to operate in either vacuum or atmospheric pressure and has 8 in. ID and 12 in. OD. While designed as E-beam monitor, unit can also measure high-frequency transients on conductor carrying high dc or ac currents with minor modifications.
Original Press Release:
Electron Beam Monitor for High Pulse Currents
Ion Physics Corporation, IPC, of Fremont, New Hampshire has designed and built an electron beam current monitor capable of measuring pulse currents up to 50,000 amperes, with a risetime of approximately 10 nanoseconds, and an output sensitivity of 10 mV/A.
This current monitor, model CM-1-E-beam, was constructed to operate either in vacuum or atmospheric pressure and has an inner diameter of 8", and an outer diameter of 12".
In general, it is difficult to design a current monitor with a 10 nanosecond response when the inner diameter exceeds several inches and the sensitivity is less than 50 mV/A. Unique to this CM-1-E-Beam current transformer is its ability to maintain a fast risetime response in spite of its relatively low sensitivity of 10 mV/A, and its relatively large inner diameter of 8".
This monitor was designed as an E-beam monitor, but with minor modifications it would be equally well suited to measure high frequency transients on a conductor carrying high DC or AC currents.
IPC has over 30 years experience in the design of current monitors. Additional information may be viewed at IPC's website at www.ionphysics.com. The price of the CM-1-E-beam unit is $1,300.00 FOB plant. Literature is available upon request.
