CP Clare's Triggergaps are high-energy spark gaps that are capable of switching stored energy in a fraction of a microsecond. Triggergaps require no standby power, are extremely rugged, and require only a low-energy, highvoltage triggering pulse. The miniature TA series (1-15kV) provides switching capability for pulses with energy content as high as 50 joules. The larger TB series (2.5-25 kV) will reliably switch pulses with up to 300 joules of energy. The TG-221 to 226 (1-60 kV) can switch pulses with energy contents of up to 6000 joules and feature adjustable self-breakdown voltages.
