Provide a new thinner target housing. A request for approval to install this item will be sent to the Neutrino Laboratory. 2} If required, make available drift chambers which are now under construct­ ion a n. E. The Universi. Oxford University is responsible forl} ~erenkov hodoscope. This is built and stored in the Muon Laboratory. It has yet to be tested. -15­ 2) Hodoscope changes. New parts will be made at Oxford and brought here for installatio ty of Illinois will supply­ 1) Twelve 1 mX1 mMWPC planes. These modules are now under construction at Urbana and will be wound at Harvard. -16­ VIII. Requests for Preparation and Beam Time 1) Access to the Muon Laboratory will be required in order to im­ plement the proposed improvements and to restore the E-98 apparatus to its muon scattering configuration following its present use for hadron experiments. We estimate that the time required is as follows: a) Modification of scintallation hodoscopes, 3 weeks. b) Installation and testing of ~erenkov hodoscope, 8 weeks. (This will be subject of a separate letter). c} Installation of lead-glass, 5 weeks. d} Installation of target and stand, commissioning of target, 6 weeks ina
