Abstract: A charge carrier multiplier structure for a light sensor, in particular an ultraviolet light sensor, is described. The charge carrier multiplier structure comprises a dielectric sheet having first and second opposite faces and having an array of holes traversing the dielectric sheet between the first and second faces, at least two photocathodes supported on the first face of the dielectric sheet that are electrically isolated from each other and which define at least two sensing regions, each photocathode having a respective work function and quantum yield and having a respective area and at least one anode supported on the second face of the dielectric sheet.

Abstract: A device (1), such as a detector or imaging device, for detecting ultraviolet light, is described. The device comprises a housing (4) for a chamber. Disposed within the housing is a charge carrier multiplier structure (9) comprising a dielectric sheet (10) having first and second opposite faces (11, 12) and having an array of holes (16) traversing the dielectric sheet between the first and second faces. The device includes a photocathode (13) supported on the first face of the dielectric sheet, having a work function of less than 6 eV. The device includes an anode (14) supported on the second face of the dielectric sheet.

Abstract: A system (200) for short-listing one or more suitable candidates for an employment role and for recruitment management comprises a data store (280) in communication with a communications network (210) for storing information relating to a plurality of potential candidates for employment in one or more roles. A processor (240) operatively coupled to the data store populates an organizational chart of an employer with information relating to one or more roles with the employer, a number of the potential candidates for each role, and a number of matched candidates for each role from the number of potential candidates to indicate a level of ease or difficulty in filling the role. Methods, apparatus and GUIs for performing the above and for short-listing suitable candidates for employment in a role are also disclosed.
