2.2.2 BEAM SHARING These tests can run parasitically upstream of other tests as the amount of material added to the beamline will be small (a few centimeters of polystyrene and GIO). There will also be the material from the CAPTAN pixel telescope, as usual. 2.2.3 RUNNING TIME The experimenters request three to four days of running for these tests. Time for setup and installation will also be required. 2.3 EXPERIMENTAL CONDITIONS 2.3.1 SETUP The detector will consist of up to six layers of 5 or 3 mm thick, 3 cm x 3 cm tiles directly coupled layer may contain just one tile or a tile and up to two of its neighbors. Each layer will be assembled as a light-tight unit with the total size of the assembly being approximately 10 cm x 10cm x 24 cm. The module will be mounted on supports allowing for its manual translation and rotation. The supports will be anchored to the pixel telescope dark box. The experimenters would need to access it every 2.5 - 3 hours to manipulate its position. MOU for Response and Unifonnity Studies ofDirectly Coupled Tiles 2.3.2 ELECTRONICS NEEDS Each tile in the module will be connected to the TB4 electronics board developed at Fennilab with a cable. Since each TB4 board accommodates four channels, three TB4 boards housed in a VME crate will be used. Space and electric power will be needed for the 6U VME crate, power supplies and cables inside the experimental enclosure. The TB4 electronics will communicate with a computer located inside the alcove counting room with an ethemet cable. 2.3.3 ACCESS Access to the beam area will be needed periodically for installation and cabling

2.4 SCHEDULE The experimenters will initiate these tests in May of 2010 and propose to continue them at a later time if required. MOU for Response and Uniformity Studies ofDirectly Coupled Tiles 'I'll. RESPONSIBILITIES BY INSTITUTION - NON

Operations Department Main Control Room (MCR). 4.1.7 Position and focus of the beam on the experimental devices under test will be under control of MCR. Control of secondary devices that provide these functions may be delegated to the experimenters as long as it does not violate the Shielding Assessment or provide potential for significant equipment damage. 4.1.8 The integrated effect of running this and other SY120 beams will not reduce the antiproton stacking rate and the neutrino flux by more than 5% globally, with the details of scheduling to be worked out between the experimenters and the Office of Program Planning. 4.2 PARTICLE PHYSICS DIVISION: 4.2.1 The test-beam efforts in this MOU will make use of the Meson Test Beam Facility. Requirements for the beam and user facilities are given in Section II. The Particle Physics Division will be responsible for coordinating overall activities in the MTest beam-line, including use of the user beam-line controls, readout ofthe beam-line detectors, and MTBF gateway computer. [0.5 person weeks] 4.2.2 The experimenters will need help in setting up a fast beam trigger counter, using components already in existence at MTBF or NIU. [0.5 person-weeks] 4.2.3 The experimenters request the integration and synchronization ofthe TB4 electronics and pixel telescope data streams such that event-by-event reconstruction of tracks passing through the scintillator tiles becomes feasible. [1.0 person-weeks] 4.3 COMPUTING DIVISION 4.3.1 Internet access should be continuously available in the counting house. 4.3.2 Assistance in incorporating the CAPTAN pixel detector readout system into the experimental architecture, ifneeded.
