Recently the applications of radioactivity in the industry and medical fields are on the rise in India, but the education in this field is mostly restricted to theory because the required experimental facilities are scarce due to the high cost of the equipment and difficulties in obtaining radioactive sources. For teaching, we need reliable, easy to maintain and inexpensive equipment, not the state of the art ones. The Alpha Spectrometer developed at Inter University Accelerator Centre is such a device. The Alpha Spectrometer consists of a small vacuum chamber, Pre-Amplifier, Shaping Amplifier and a 512 channel MCA with USB interface. The unit is powered by a 12V DC adapter.
