Chapter 6: Test beam specifications 6–158 Figure 6.11: Placement of upstream (left) and downstream (right) CRT panels with respect to the detector. Each panel consists of eight modules (light green). This shows a possible assembly in which the upstream side has two panels and the downstream side has one. Full coverage of the detector faces would require eight four-module units. The panels can be moved laterally along the support structure shown. Figure 6.12: Drawing of one 64-strip CRT module (one 32-strip layer shown). Each module contains two layers of 32 5-cm × 1-cm × 320-cm strips with wavelength-shifting fibers. The 64 fibers for each module are coupled to a Hamamatsu M64. ProtoDUNE Single-Phase Technical Design Report Chapter 6: Test beam specifications 6–159 Figure 6.13: Photo of CRT module. The inset shows the front-end board attached to the PMT and module. The two large chips are the MAROC2 and an Altera FPGA. ADC, providing pulse height information for hit strips. The readout of each module is self-triggered. Each module requires a 62.5-MHz clock and a sync pulse. The sync pulse is a NIM signal with a frequency between 0.5 and 0.05 Hz. The sync signal is used to reset the internal counter of each module. Each module produces a single NIM trigger output indicating the presence of a muon-like signal (i.e., overlapping hits in the two module layers). 6.4.3 Layout of CRT modules The ProtoDUNE-SP CRT is based on units of four modules, layered and oriented orthogonally as shown in Figure 6.14). These four-module units result in a 3.2-m × 3.2-m area. Figure 6.15 is a photograph of an actual unit. Tests are currently underway to evaluate two schemes for holding the modules. Following these small-scale tests, a full prototype structure with a real module will be constructed and tested in Chicago. Possible locations for modules parallel to the upstream and downstream faces of the cryostat are under investigation. The CRT installation must preserve access to the outside of the cryostat, either by leaving sufficient fixed space between the detector and the panels or by sliding panels out of the way. The panels must also avoid existing infrastructure. An appealing option for the upstream face is to make use of some of the existing APA rails. It is anticipated that a rails-and- hanger system identical to the APA design for both the upstream and downstream CRT modules will be used, as illustrated in Figure 6.11. In the possible arrangement shown in the figure, which employs 24 modules (six four-module units), data is taken with the downstream modules first in one position then the other, to cover the full TPC volume. ProtoDUNE Single-Phase Technical Design Report Chapter 6: Test beam specifications 6–160 Figure 6.14: Illustration of orthogonal layout of a four-module CRT unit, providing 2D readout. Two modules are in back (landscape orientation in diagram), with the inactive portion for the fibers, PMTs, and readout electronics at right; two modules are in front (portrait orientation), with the inactive portion at the top. A support structure sits between the front and back modules (grey and brown grid); additional support is provided on both outside surfaces by structures that clamp the modules to the inside support. The outer support for the front modules is shown in green. ProtoDUNE Single-Phase Technical Design Report Chapter 6: Test beam specifications 6–161 Figure 6.15: Photo of fully assembled four-module layout at Double Chooz. The top modules are oriented lower right to upper left in the photo; the inactive portions of the bottom modules can be seen in the lower left and center. 6.4.4 DAQ and readout The CRT uses its own readout. This readout produces a series of ADC values and time stamps for hit strips, and makes use of a ProtoDUNE-SP global clock and sync pulse to enable merging with TPC information – pseudo-online – using time stamps. Note that the entire CRT system is isolated from the detector ground; it uses the building ground. 6.4.5 Testing of modules during installation All modules, PMTs, and front-end readout boards have been fully tested. Prior to installa- tion, QA/QC procedures identical to those used for the Double Chooz installation will be used. Each module is first equipped with a reference PMT and front-end board. Using the same well- characterized PMT + readout board for all modules allows efficient checking for light leaks and other module defects. Once the light-tightness and proper function of the module is verified, the final PMT and PMT board are installed. The function of the PMT/PMT-board combination and the light-tightness of the PMT installation is checked before the module is put into position.
