2. "Jul01 Baseline" (1) The gap is now officially increased by 4 cm. All previous gap studies had been done by moving only the front face of the endcap back and leaving the back end where it was (thinning the calorimeter). So it took some editing to propagate the 4 cm offset to the front of the JF shield. (2) The inner bore of the JD is copper, and is tapered along the same eta line as the rest of the forward shielding (not cylindrical). (3) The ion pump in front of the FCal is now the stainless steel model suggested by Ian. (4) The borated poly in the JT tapers from a thickness of 7 cm at the front to 4 cm at the back. This is in hopes that we could optimize the CSC region for neutrons and photons, and the middle MDT's for high energy hadrons in the same solution. Although modeled as a taper for convenience, this could no doubt be stepped-cylindrical and give the same results if it turns out to be a good solution. 10.
