WH 9/7/94 In the following, the outline of the TDR and the authors responsible for the various chapters are listed. The outline of the TDR will be very similar to our Proposal. The LaTEX style file as well as an updated and corrected example can be found on our ftp account, subdirectory TDR. ftp x4u2.desy.de anonymous blabla cd /pub/herab/tdr get example.tex get example.ps get herab.sty get macros.tex bye -------------------------------------------------------- o Introduction WH+TL+... o Overview of the experiment o New aspects in the detector design o Update on physics perspectives o HERA-B Experiment o Proton beam line Sen, Parker, MPY ??? o Target Lohse/Knoepfle o Beam pipe Knoepfle ?? o Magnet Schmidt-P. o Vertex detector Knoepfle o Inner tracker Eisele o Outer tracker Kapitza o RICH Krizan o Forward TRD Dolgoshein o Calorimeter Golutvin o Muon system Zaitsev o Frist-level trigger Schulz o Second-level trigger Medinnis o DAQ system and third-level farm Zweizig/Zeuthen o Experimental area Spengler o Installation Spengler o Safety Albrecht o Software and data analysis Albrecht o Performance summary ASW+WH+... o Summaries ASW+JS+TL+WH o Cost summaries o Schedule summaries o Responsibility and organization: The following is supposed to serve as an outline for the TDR detector chapters as well as for the cost and manpower summaries. The goal was to list, in a somewhat generic fashion, but yet in some detail, the main keywords associated o with the description and definition of a detector o with its costs, either direct or through external labor o with the manpower needs o with the time schedule of the production The keywords refer to the preparation for the production, the production itself, the tests and quality assurance, and the transport and installation. Usually not included is generic R&D. Obviously, not all keywords apply in all cases, and special items may be missing entirely - the outline can only serve as an approximate guide line. I think that the identical outline and set of keywords can be used to structure the presentation in the TDR, to estimate the costs, the manpower needs, the timing, and to define milestones. With most keywords one can associate a "cost" per unit, a number of units, and a total "cost", where "cost" means either and "unit" means DM a detector part or (external) service or hours engineer, technician, or worker time or hours or days real time used for production which can than be represented using e.g. the CORE tools. In our summaries of costs, we will usually list only the two top levels (1., 1.1). Levels like 0.* or *.0 are not included in the cost summary. Lower levels are meant to remind you of possibly relevant items, and should be included in the documentation for our internal use. With a subdetector as a \section, the highest-level divisions (1.) would naturally correspond to \subsections of the TDR. Please use \subsubsection* instead of \subsubsection for the next level (1.1). In this case, the subsubsection will not be included in the table of contents. -------------------------------------------------------------------------- A first (sub-)section is only used for TDR presentation, and not associated with cost etc: 0. Component overview {should not repeat general design considerations, but instead refer to the proposal} 0.1 (Brief) description of component General description, also outlining the following presentation Overview plot, maybe 3-D view Type, number... of (modular) detector elements Detector lifetime, replacement strategies Table with key properties, if appropriate 0.2 Overview of changes/progress since proposal Technology choices, if any Aspects and results of the optimization of component, with respect to performance and cost 0.3 (Brief) update on performance --------------------------------------------------------------------------- 1. Basic detector elements {obviously very detector specific} 1.1 Basic (modular) detector element/subassembly {e.g. a Silicon module, a tracking chamber section} 1.2 Signal collection, routing to electronics boards/hybrids 1.3 Assembly procedure, tools, templates 1.4 Quality control, testing procedures and tools 1.5 Detector lifetime, replacement, recycling, cleaning... -------------------------------------------------------------------------- 2. Mechanics and support structure 2.1 Assembly of detector elements {e.g. to a tracking superlayer} Basic mechanical structure Mechanical, thermal stability Alignment/adjustment procedures, jigs, tools Heating, cooling, other utilities Servicing and repair of detector elements 2.2 Mounting of detector units in the spectrometer Mechanical design Mechanical, thermal stability and reproducability Servicing and access --------------------------------------------------------------------------- 3. Readout system {Note: readout system for a detector should include everything detector specific, such as the readout boards with the buffering for 2nd level trigger latency, and the output to the 1st and 2nd level triggering, if applicable. Do NOT include the VME crates, the readout controller CPU, and the fast links to the event builder; those are included in the DAQ. Of the readout boards, part will be detector specific (the connection to the front end, the ADC, sparsification...), whereas the buffers and buffer control will (hopefully) be a DAQ standard. However, it didn't seem to make sense to split the board costs among detectors and DAQ, and we include the total cost in the detector.} Beware that in most circumstances special (halogen-free) cables have to used! 3.0 Electronics chain overview Front-end amplification, processing, pipelining On-detector crates, processors DAQ readout boards Control and synchronization 3.1 Front-end {everything right on the detector unit itself} Electronics motherboard or hybrid Front-end signal processing Level-1 trigger signals Front-end pipeline Readout following level-1 trigger Interface, cable drivers BX, readout synchronization, readout control Gain, time calibration Lifetime, replacement, recycling issues 3.2 On-detector crates/processors {some detector will have intermediate boards/crates mounted near the detector for data conditioning and processing} Control interface to front-end ADC, where appropriate Zero-suppression and formatting (hardware/DSP) Trigger/control-bus interface Interface to DAQ board Crates 3.3 Readout boards {receiver/converter boards in the DAQ crates} Control interface to front-end ADC, where appropriate Zero-suppression and formatting (hardware/DSP) Level-2 data link driver Level-2 buffer memory Trigger/control-bus interface VME interface 3.4 Signal interconnects Front-end to on-detector crates Cable type, #, length Connectors Manufacturing, test (internal/external?) {Cable bridges etc. need not be included} On-detector crates to DAQ crates Cable type, #, length Connectors Manufacturing, test (internal/external?) {Cable bridges etc. need not be included} Cable routing issues 3.5 R&D, Prototyping Prototype readout and DAQ Custom component development (Asics, Hybrids etc.) Custom cable, connectors, etc? 3.6 Quality control Test of components Test of sub-assemblies (daughterboards etc.) Test of boards/modules Hardware and software for quality control Costom test stations General-purpose tools such as Probe stations, waveform generators, logic analyzers Semiconductor test stations,... --------------------------------------------------------------------------- 4.

Slow control {There will usually be a workstation/PC for slow control and monitoring in the counting room. This, plus the (most likely Ethernet} connection between this unit and the detector is included in the general DAQ. In many cases, control tasks can be handled by the Readout Controller CPU (also in the DAQ). Included with the detector is only detector-specific stuff, plus additional controllers} 6.1 Interface modules To low-voltage supply To high-voltage supply To gas-system controllers To interlock system 6.2 Additional sensors (temperature, etc.) 6.3 Cables and connectors 6.4 Slow-control crates (if separate from DAQ) 6.5 Slow-control CPU (if separate from DAQ) 6.6 (Front-end) control software 6.7 Prototype systems --------------------------------------------------------------------------- 7. Alignement system (very detector specific) --------------------------------------------------------------------------- 8. Transport, Installation, Replacement 8.1 Transport Packaging Special transport fixtures Special gear, cranes etc. Transport costs 8.2 Installation Pre-installation tests Special gear, templates ... Cabling of the detector Gas, utility connections Survey, surveying tools Post-installation tests 8.3 Replacement strategies Frequency of replacement Replacement procedures ---------------------------------------------------------------------------- 9.
