5. Magnets developed for BARC Mass Spectroscopy applications:
Mass spectrometers with sector field magnetic analyzer is routinely used for the high precision & accurate isotope ratio measurements of nuclear materials. AMTD has designed and developed ten numbers of mass spectrometer analyzer dipole magnets and delivered to Technical Physics Division (TPD), BARC. Recently, two analyzer dipole magnets have been developed whose details are given below.
