Motivation
• Goal is to test future CMS vertex detector prototypes:– Diamond sensors– 3D sensors– MCz planar silicon sensors
• We compare against the current CMS silicon detector standard:– The telescope is made of grade B modules
rejected during CMS pixel production.

Since Fall 2009…
• Integrated the analysis software into telescope package.
• Expanded the telescope by doubling station count.
• Built a new modular mechanical box that hosts the detectors and electronics.
• Collaborated with universities interested in applicable sensors.

Diamond Sensor Charge Sharing vs. HV
Number of Columns per Cluster
Number of Rows per Cluster
HV = -250 V
Sensor rotated to ~ 20 in row direction. More charge collected with higher bias HV till saturation. Need more work on gain calibration to extract the absolute
charge (MPV of Landau distribution).

Preliminary
![Page 21: SLHC Sensors at Meson Test Ryan Rivera ESE/CD, Fermilab All-Experimenter’s Meeting April 19, 2010.](https://reader034.fdocuments.net/reader034/viewer/2022051820/56649e9e5503460f94b9f6da/html5/thumbnails/21.jpg)
Diamond Sensor Residual Center vs. HV
Tracks are at ~ 20 with respect to normal of sensor plane in row direction. Use the same set of telescope spatial configuration parameters. With low bias HV, charges generated near readout electronics can be collected,
equivalent to thinner effective sensor. Thus the residual center shifts. The maximum possible shift ~ tan(q)*d/2 ~ 90 mm.

Future Plans
• Analyze data from 3D sensors.• Augment telescope with higher resolution
planes – possibly strips or CCDs.• Improve charge resolution and analog stability
by adding amplifiers.• Continue to improve usability of telescope
software package.

Future Plans – Parallel Processing
• Alignment and Reconstruction done in Real-Time.
• Integrate with xTCA.• Explore CUDA and
compare results.
