“…A 9-sector, zero gradient magnet is designed in order to achieve the same compression ratio of 10:1 with reduction in the size of the magnet. As described in the paper by D. Tronc et al [4], an electron beam is made to rotate twice through 5-sector magnet. Thus essentially beam is rotated through 720 • .…”

This facility will include neutron activation of sodium by photo neutrons for FBR shielding studies and Time of Flight (n-TOF) facility for various research applications. The n-TOF facility consists of electron gun that will generate 10 ns electron beam. It will be accelerated to 30 MeV by RF linear accelerator. The electron pulse at the exit of the linac will have 40% energy spread. A compression magnet is designed to compress 10 ns, 10 A electron pulse to 1 ns, 100 A. A 360 0 , 5-sector, zero gradient magnet having rectangular yoke of size 3.2, m × 2.7 m × 0.4 m and weight of ~24 Ton gives pulse compression ratio of 10:1 at a magnetic field of 0.1 T.In order to get the same compression ratio with reduced magnet size, a 720 0 , 9-sector magnet having zero magnetic field gradient is designed. A magnet will have five physical sectors through which an electron beam will rotate twice. The analytical solution and CST Particle Studio simulation results are presented. To get 10:1 compression ratio, ~0.15 T magnetic field will be required and overall magnet size will be reduced to 2.1, m × 2.1 m × 0.4 m.

A n-TOF experiment requires 1 nsec duration pulses to get better energy resolution. The paper presents the design of a compression magnet that can compress a 10 nsec electron pulse to ∼ 1 nsec having energy variation from 18–30 MeV. A zero gradient, 5-sector magnet that will bend the beam through 348° is designed for the same. The beam dynamics to calculate energy spread, design of sector magnet and the simulation results of CST particle studio are presented. A combination of magnetic fields 0.1 T, 0.05 T and 0.02 T in different sectors of the magnet give the compressed pulse width of ∼ 1.3 nsec.
