Is. Balakrishnan et al., THYRATRON PERFORMANCE - DEPENDENCE ON MOUNTING IN A MEDICAL LINEAR-ACCELERATOR, British journal of radiology, 68(815), 1995, pp. 1242-1243
A thyratron is an important component of a medical linear accelerator.
The working life of a thyratron has been found to be dependent on its
physical orientation in the accelerator. This observation is a result
of maintaining accelerators for over 15 years.
