A suc­cess­ful de­vel­op­ment of a 6 MeV elec­tron ra­dio­ther­a­py ma­chine at SAMEER, India was re­port­ed ear­li­er*. Now a 15 MeV elec­tron linac pro­to­type is de­signed, de­vel­oped and test­ed at our site. We have mea­sured a beam cur­rent of 80 mA at the X-ray tar­get at­tached to the linac. En­er­gy gained by elec­trons in a cav­i­ty chain of about 1.2 m length is mea­sured to be more than 15 MeV using a 6 MW klystron power source. An RF win­dow ca­pa­ble of han­dling 12kW av­er­age power is at­tached to the linac tube and it is cooled by water. The final linac pa­ram­e­ters mea­sured were at par with the de­signed val­ues. A high volt­age mod­u­la­tor and con­trol con­sole for the linac are de­signed and de­vel­oped in house. This paper will de­scribe key as­pects of the de­sign and de­vel­op­ment pro­cess of the com­plete sys­tem. Also fu­ture ap­pli­ca­tions are planned like-du­al en­er­gy dual mode linac for ra­dio­ther­a­py, cargo scan­ning sys­tem and com­pact comp­ton X-ray source using this tech­nol­o­gy is briefed in this paper.
