He has made significant contributions to the field of vacuum systems, particularly through his innovative designs and patents. With a total of 2 patents, Parry has demonstrated his expertise and commitment to advancing technology.

Latest Patents

Parry's latest patents focus on the development of a pnictide trap for vacuum systems. The first patent describes a fore line trap that is strategically located before the forepump in a vacuum system. This trap utilizes a cracker, which can be a heated filament or a plasma, along with cold walls to effectively crack pnictide gas species such as P.sub.4 into P.sub.2. This process results in a higher sticking coefficient, allowing the pnictides to be deposited on the cold walls. The design includes a removable sleeve that can be replaced with a clean one for maintenance purposes.

The second patent also addresses the need for a trap for vapor species, specifically pnictide.sub.4 vapor species, within a vacuum system. This invention can be positioned either within the vacuum chamber or between the vacuum chamber and the forepump. The trap features a housing for a cracker that cracks the pnictide vapor species into pnictide.sub.2. The cooled walls of the housing facilitate the formation of a film that adheres to the walls, preventing harmful pnictide.sub.4 vapor species from entering the forepump. A removable sleeve is also incorporated for easy maintenance and replacement.
