Spherical neutron polarimetry (SNP) is made possible by replacing the
simple adiabatic coil arrangement used on IN20 for classical uniaxial
polarisation analysis (UPA) with the zero-field polarimeter called Cry
opad. Cryopad II represents the current state of this unique facility
and it features numerous practical improvements relative to the protot
ype Cryopad I. Most noticeable is the new monolithic design which incl
udes a large room temperature vertical sample well. The calibration of
Cryopad-II, based on a single nuclear Bragg reflection, turns to be r
emarkably easy and simple. (C) 1998 Elsevier Science B.V. All rights r
