ASPIRE

The research facility at IUAC provides a dedicated Radiation Biology Beam line equipped with the irradiation system called ASPIRE [Automatic Sample Positioning for Irradiation in Radiation Biology Experiments].

This is a computer controlled system that enables one to irradiate cells placed on 35 mm petri dishes kept in medium in a sterile condition one after another at quick succession with predetermined particle dose.

The uniformity as well as fluence verification has been done using irradiating SSNTD [CN-85] and subsequent etching. The tracks were counted using microscope over accurately measured areas across the entire irradiation field of 40 mm diameter. The uniformity over a field of 40 mm diameter is having 2 % standard deviation. The mean fluence is within 1 % of the electronically measured value at the centre of the field.
