Kimball Physics, Inc. Basic ELG-2/EGPS-1022 unmounted System ELG-2 / EGPS-1022_2 电子枪

Electron source, Power Supply and 3m Cable Set when ordered together; 

Energy: 1 eV to 2k eV

Beam Current: 1nA to 10μA

Spot size: 0.5mm to 5mm

Ta disc cathode installed standard [up to 1 x 10-5 torr]

Energy sweeping capability.

4-pole electrostatic deflection: ±2.5 degrees at 2000eV; scales larger at lower energies

Fast Pulsing Capability: Pulse Generator is required. Ultra High Speed Pulse Generator Pulse widths 20ns to 100 μs,rep rates up to 20% duty cycle. ECC not usable simultaneously. Best results when used with flange mounted gun.

Please specify length of housing on the order (Sealing surface to end): Standard: 150 mm; Possible Range: 110 mm to 300 mm. Non-standard length, . For low energy operation, the recommended end-of-housing to target is 20 mm. Even the earth’s magnetic field can deflect the beam at longer distances. Smaller spots are more easily obtained at shorter working distances.

Energy Hi-Low Range included: Hi 2000.0 Volts max. Low 0 to 200.00 V. Can be set to within 10 millivolts. Accuracy: 100 millivolts. Can be set to start under 10 millivolts
