ATLAS SCT Hybrids Experience
نویسنده
چکیده
The hybrids of ATLAS semi-conductor tracker (SCT) were made with Cu/Polyimide flex-circuits, reinforced with carbon-carbon substrates, in the barrel and in the endcap modules. We report successes, problems and solutions in the course of production of 2600 pieces of hybrids each.

Results of early phase of series production of ATLAS SCT barrel hybrids and modules
A status of early series production of the barrel hybrids and modules of the ATLAS Semiconductor Tracker (SCT) is reported. 120 hybrids (with ASIC’s) and 98 modules were fabricated in Japan by the mid. August 2002 and gone through extensive quality assurance tests. Defective channels were found much less than 1% in hybrids and still less than 1% in modules. No increase of defective channels was...
متن کاملDiagnostic Analysis of Silicon Strips Detector Readout in the ATLAS Semi-Conductor Tracker Module Production
The ATLAS Semi-Conductor Tracker (SCT) Collaboration is currently in the production phase of fabricating and testing silicon strips modules for the ATLAS detector at the Large Hadron Collider being built at the CERN laboratory in Geneva, Switzerland. A small but relevant percentage of ICs developed a new set of defects after being mounted on hybrids that were not detected in the wafer screening...
متن کاملGenerating the synthetic CT (sCT) and synthetic MR (sMR: sT1w/sT2w) images of the brain using atlas based method
Introduction: Radiation therapy planning (RTP) is one of the clinical applications in which both CT scan and MRI are used. MR and CT images are applied to determine the target volume and calculation of dose distribution, respectively. In addition, using two imaging modalities increases the department workload and cost. In this study, an algorithm was presented to create synthet...
متن کاملGenerating Synthetic Computed Tomography and Synthetic Magnetic Resonance (sMR: sT1w/sT2w) Images of the Brain Using Atlas-Based Method
Introduction: Nowadays, magnetic resonance imaging (MRI) in combination with computed-tomography (CT) is increasingly being used in radiation therapy planning. MR and CT images are applied to determine the target volume and calculate dose distribution, respectively. Since the use of these two imaging modalities causes registration uncertainty and increases department w...
متن کاملApplication of Cu-polyimide flex circuit and Al-on-glass pitch adapter for the ATLAS SCT barrel hybrid
We applied the surface build-up Cu-polyimide flex-circuit technology with laser vias to the ATLAS SCT barrel hybrid to be made in one piece from the connector to the electronics sections including cables. The hybrids, reinforced with carbon–carbon substrates, provide mechanical strength, thermal conductivity, low-radiation length, and stability in application-specific integrated circuit (ASIC) ...
