P3He) The He3Transmission function returns the unpolarised beam transmission of a 3He spin filter for a given neutron wavelength. The unpolarised beam transmission is defined by the equation below where p is ... lbdaSDev, P3HeSDev) The He3TransmissionSDev function returns the standard deviation of the unpolarised beam transmission of a 3He spin ...

front of the neutron guide crossing the "casemate" wall, and after the beam monitor and attenuator, there is a remotely controlled beam-defining aperture. The control box for this unit is in the instrument ... the mirror. Their direction can be made co-axial to the incoming neutron beam, thus faciltitating the setup of the sample in the beam. 7. ...
