  Here, we report our first step towards tackling this issue at the roots by irradiating the pharmaceutical effluents from a stages of their existing treatment plant with an Electron Beam (EB) with doses varying from 25 kGy to 200 kGy. We have used a normal conducting pulsed wave linear accelerator developed by SAMEER. It produced a pencil beam of electrons of energy 6 MeV with an average current of 16 micro-Ampere. To ensure optimum dose delivery, Fluka-Flair Simulations have been used. We have successfully demonstrated that electron beam irradiation along with the use of conventional techniques like coagulation after the irradiation can further increase the efficacy of the process with a final reduction in Chemical Oxygen Demand (COD) to be as large as 65% in some of the cases.

  The design and optimization of the proposed 1.3 GHz gridded thermionic electron gun aims to drive a conduction cooled superconducting electron accelerator that will be used to treat contaminants of emerging concern in water bodies. The gun geometry is Pierce-type and optimized for beam current of 1A with LaB6 as cathode material at cathode potential of -100 kV. The final optimized cathode radius and angle of inclination of the focusing electrode are found to be 1.5 mm, and 77 degree respectively. For an emittance compensation electrode, the optimized values for thickness and potential are 2 mm and -50 kV respectively, and separation between cathode and compensator is 8 mm. Beam dynamics calculations have been performed with self-developed particle tracking code that assumes space charge interactions and imported fields. The beam dynamics simulations show that with an initial bunch length of 50 ps having a bunch charge of 5 pC, the bunch length of the bunch reduces to 33 ps. The diameter, transverse and longitudinal emittance obtained are 2.8 mm, 1 mm-mrad and 5 mm-mrad respectively.
