(A) Schematic diagram of the Dingo beamline¹⁰. SS = secondary shutter; TS = tertiary shutter; FT = flight tube; PFBS = pre-flight tube beam slits; FRM = floor rail mounting; DB = detector box; BS = beam stop. The relative positions of the sample stage and irradiation position are indicated. (B) Sample mount designed for holding tissue culture plates vertically positioned within the neutron beam at the irradiation position. Samples are loaded onto this mount before being driven up to the irradiation position immediately behind the tertiary shutter. The modular design allows for various sample formats to be mounted and positioned for irradiation.
