This allows us to probe nanoscale structural changes on the timescale of ms to hours. Time of Flight SANS is ideal for these measurements as a large lengthscale range can be studied in one shot. Data collection is synchronized with the kit and automatic cycling is used to improve statistics. Event mode has now been commissioned on Sans2d – each neutron has it’s own time stamp and so data can be ‘time sliced’ after the measurement has been taken. Temperature range -10-80 degrees C.
