The HIS 13 is a flange mounted and easy to integrate vacuum ultraviolet photon source for standard and advanced photoelectron spectroscopy applications.
The excellent performance, ease-of-operation and it´s robust design makes the HIS 13 VUV light source an excellent choice for ultraviolet photoelectron spectroscopy.
The operation of the lamp is based on a cold cathode capillary discharge. There is a windowless direct sight connection between the discharge area and the target. The discharge current is electronically stabilised.
The lamp is water cooled in order to allow for high discharge currents (up to 300 mA) and optimum uptime.
The HIS 13 can be operated with various discharge gases, such as helium, neon, argon, krypton, xenon or hydrogen. In many applications it is operated with helium in the He I mode delivering a very narrow (1...3 meV) emission line at 21.2 eV (584 nm) that is commonly used for standard UPS.
A choice of light capillaries and an optional 3rd pumping stage allows configuring the source according to the experimental requirements (photon flux vs. operating pressure etc.)
An integral portaligner faciliates the positioning of the light spot on the sample in a range of ± 3°.
