Detailed Description

Corrects the input workspace for helium3 tube efficiency based on an exponential parameterization.

The algorithm expects the input workspace units to be wavelength. The formula for the efficiency is given here.

\[ \epsilon = \frac{A}{1-e^{\frac{-\alpha P (L - 2W) \lambda}{T sin(\theta)}}} \]

where \(A\) is a dimensionless scaling factor, \(\alpha\) is a constant with units \((Kelvin / (metres\: \mbox{\AA}\: atm))\), \(P\) is pressure in units of \(atm\), \(L\) is the tube diameter in units of \(metres\), \(W\) is the tube thickness in units of \(metres\), \(T\) is the temperature in units of \(Kelvin\), \(sin(\theta)\) is the angle of the neutron trajectory with respect to the long axis of the He3 tube and \(\lambda\) is in units of \(\mbox{\AA}\).
