Detailed Description

Returns efficiency of cylindrical helium gas tube.

wvec Final neutron wavevector (Angsstrom^-1) rad Outer radius of cylinder (m) atms Pressure in number of atmospheres of 3He t2rad Ratio of thickness of tube wall to the radius sintheta Sine of the angle between the cylinder axis and the directin of travel of the neutron i.e. sintheta=1.0d0 when neutron hits the detector perpendicular to the cylinder axis.

T.G.Perring June 1990:

Algorithm is based on a combination of Taylor series and asymptotic expansion of the double integral for the efficiency, linearly interpolating between the two in region of common accuracy. Checked against numerical integration to yield relative accuracy of 1 part in 10^12 or better over the entire domain of the input arguments

T.G.Perring August 2009:

Added generalisation to allow for arbitrary direction of path of neutron with respect to the cylinder.

Origin of data for 3He cross-section

CKL data : (Argonne) "At 2200 m/s xsect=5327 barns En=25.415 meV " "At 10 atms, rho_atomic=2.688e-4, so sigma=1.4323 cm-1"

These data are not quite consistent, but the errors are small : 2200 m/s = 25.299 meV 5327 barns & 1.4323 cm-1 ==> 10atms of ideal gas at 272.9K but at what temperature are the tubes at "10 atms" ?

Shall use 1.4323 cm-1 @ 3.49416 A-1 with sigma prop. 1/v

This corresponds to a reference energy of 25.299meV, NOT 25.415. This accounts for a difference of typically 1 pt in 1000 for energies around a few hundred meV.
