Linac System

The function of NSRRC Linear accelerator (LINAC)­ is to generate electrons by a hot cathode gun and accelerate them through one or three linear accelerating sections to 50 MeV for TLS and to 150 MeV for TPS, respectively. The main subsystems include electron gun, buncher, accelerating sections, vacuum system, and focusing and steering magnets.



The NSRRC pulsed power supply system (pulse-PS) provides various types of pulse-PS units with specifications (or equivalent) listed as follow:

Categorizing by their capability of delivered peak current, pulse shape base-width, they are:

  1. IGBT kicker PS: 500 A, flat-top, 1 µs;
  2. Half-sine kicker PS: 5 kA, half-sine, 5 µs;
  3. Septum PS: 10 kA, full-sine, 600 µs;

Specifications and typical output examples:

1. PFN kicker PS:


2. Half-sine kicker PS:


3. Septum PS:
