Database entry of irradiation data

This entry discusses challenges faced in managing irradiation data for sensors, diodes, and minisensors. Proposed solutions include introducing composite actions, new database tables, and XML tables for improved data tracking. Implementation steps and impending actions towards database enhancement are outlined, focusing on integrating agreed-upon tables and manual finalization through software proposals.

  1. Database entry of irradiation data • PROBLEMS • New form of DB data • One set of data may de-qualify whole batch of sensors  composite of composite action: NEW • Tests are done on teststructures  TS is NOT a database object  • Even worse: diodes and minisensors on TS  • how to name? WHERE to register? •  in addition there will be modules to be irradiated. • FACT: The PQC centers will face the same problem

  2. Steps to go, and possible solution • The composite of composite action has to be introduced in the DB scheme • IQC and also PQC tables could be inserted in the QTC existing DB objects • Addition of new tables • Optional, since only a fraction will be irradiated • M200 and pre-series is approaching fast! • Many pre-series sensors are delivered and tested

  3. Preliminary Irrad tables already exist in XML • Tables are done and already underwent one iteration between Karlsruhe and Louvain • We will have 3 simple tables: • diodeminisensorsensor • Tables show the results from the agreed measurements: ONE Ramp, values @Vbias=400V, difference of values before and after irradiation @Vbias=400V

  4. DB content (for sensor & minissensor) • ENV: Date,Time;Irrad_Date;Comment;Humidity,Temp Duration; operator; location; status • GLOBAL: I_TOT, V_dep; C_TOT; alpha (before and after irrad) • IRRAD-SPECS: fluence(p,n); dose(p,n); energy(p,n) • STRIP-PARAMETERS: X* [Rpoly;Cint;Ileak;Rint (CAC optional)]@Vstandard =400V Delta of all strip parameters before and after irrad • Raw Data: IV,CV, ONE RAMP {Rpoly;Cint;Ileak;Rint (CAC optional)} vs. Voltage

  5. Tables for diode Tables for sensors and minisensors are similar but more extensive.

  6. Addition for sensor and minisensor <result name="Rpoly_V1_MOhm" value=„1.7 1.67 1.72 1.72 ..."/> <result name="Rpoly_delta_V1_MOhm" value=".10"/> <result name="I_strip_V1_nA" value="552.00"/> <result name="I_strip_delta_V1_nA" value="0"/> <result name="C_ac_V1_pF" value=„500.00"/> <result name="C_ac_delta_V1_pF" value="0"/> <result name="C_int_1Mhz_V1_pF" value=„3.1 3.1 3.1"/> <result name="C_int_1MHz_delta_V1_pF" value=0"/> <result name="R_int_V1_MOhm" value="552.00 500 520 "/> <result name="R_int_delta_V1_MOhm" value="552.00"/> <result name=„Voltage_V" value=„10 20 30 .....540 550"/> <result name="C_tot_pF" value="22530.00 21370.00 ..... 1855.00 1855.00"/> <result name="Rpoly_MOhm" value="52.10 95.48 ...... 194.36 194.94"/> <result name="C_int_1MHz_pF" value="52.10 95.48 .... 194.36 194.94"/> <result name="I_strip_nA" value="0.32 0.33 ...... 0.32 0.29"/> <result name="C_ac_100Hz_pF" value="52.10 95.48 ........194.36 194.94"/> <result name=„R_int_MOhm" value=„0.68 1.38........100.00100.00"/> </action>

  7. Pending Actions • Agreement how to label tables for diode, sensor, minisensor!?! Is the diode, the irrad. Sensor and the minisensor a component of the sensor (same ID)? YES!!!!!! Are they seperate objects; where will they be registered? NO!!!!!!!!! • @DB people implementation of the „composite of composites“ • Implementation of the agreed! Tables into the DB (discussion underway) • Labview vi for the XML output (will be done by KA) • FINAL OK: MANUALLY (proposal from software)
