Dear Users,

1. A new function TouschekLifetime is introduced. It interpolates the data calculated by EMIT or Emittance[]. There are three ways of usage:

TouschekLifetime[Infinity, Infinity, nz]: Touschek lifetime in seconds with momentum aperture nz * SIGE.

TouschekLifetime[nx, Infinity, nz]: Touschek lifetime in seconds with acceptance 2Jx/(nx * (EMITX+EMITY)) + 2Jz/(nz * EMITZ) < 1

TouschekLifetime[nx, Infinity, nz]: Touschek lifetime in seconds with acceptance 2Jy/(ny * (EMITX+EMITY)) + 2Jz/(nz * EMITZ) < 1

EMIT or Emittance[] with INTRA must precede TouschekLifetime.
