Detailed studies of full-size ATLAS12 sensors

Popis výsledku v původním jazyce

The &quot;ATLAS ITk Strip Sensor Collaboration&quot; R&amp;D group has developed a second iteration of single-sided n(+) -in-p type micro-strip sensors for use in the tracker upgrade of the ATLAS experiment at the High Luminosity (HL) LHC. The full size sensors measure approximately 97 x 97 mm(2) and are designed for tolerance against the 1.1 x 10(15) n(eq)/cm(2) fluence expected at the HL-LHC. Each sensor has 4 columns of 1280 individual 23.9 mm long channels, arranged at 74.5 mu m pitch. Four batches comprising 120 sensors produced by Hamamatsu Photonics were evaluated for their mechanical, and electrical bulk and strip characteristics. Optical microscopy measurements were performed to obtain the sensor surface profile. Leakage current and bulk capacitance properties were measured for each individual sensor. For sample strips across the sensor batches, the inter-strip capacitance and resistance as well as properties of the punch-through protection structure were measured. A multi-channel probecard was used to measure leakage current, coupling capacitance and bias resistance for each individual channel of 100 sensors in three batches. The compiled results for 120 unirradiated sensors are presented in this paper, including summary results for almost 500,000 strips probed. Results on the reverse bias voltage dependence of various parameters and frequency dependence of tested capacitances are included for validation of the experimental methods used. Comparing results with specified values, almost all sensors fall well within specification.
