Title: Douglas S. Holmes: Innovator in Particle Beam Technology

Introduction

Douglas S. Holmes is a notable inventor based in Shirley, NY (US). He has made significant contributions to the field of particle beam technology, holding 2 patents that showcase his innovative approach to engineering.

Latest Patents

One of his latest patents is the "Cast Charged Particle Drift Tube." This invention involves a linear accelerator drift tube formed by a casting technique. The design includes coolant circulating grooves that are integrally formed in the central body of the drift tube as well as the face plates. This innovative feature minimizes the temperature of the drift tube in an operating environment, thereby maximizing the R.F. efficiency of the unit. The face plates are attached to the central body of the drift tube using a solder/electroform joining method. Additionally, the stem of the drift tube includes concentric passages integrally formed in the cast central body, which enables efficient circulation of coolant through the drift tube.

Another significant patent is the "Solder-Electroformed Joint for Particle Beam Drift Tubes." In this invention, the face plates of a drift tube have their joints with a central cylindrical body sealed using two metallurgical techniques. The first technique involves soldering the interface surfaces at the joints between the face plates and the body. This soldered joint prevents the entry of electroplating solution into the interior of the drift tube during a second metallurgical procedure, which involves the electroformation of a copper strap around the joint. This process provides a permanent seal against leakage of coolant from the drift tube while ensuring excellent electrical and thermal conductivity across the surface of the drift tube.
