• Experience:

• FPGA Firmware for TileCal Demonstrator: FPGA Firmware was developed for the ATLAS Hadronic Tile Calorimeter (TileCal) Phase-II upgrade TDAQ system. The Xilinx ISE Design suite and Vivado environments were used to develop firmware for the TileCal Demonstrator Read Out Link and Control Board (Daughterboard) and Tile Preprocessor (TilePPr). The Daughterboard interfaces the inner detector electronics with the TilePPr situated off-detector. The firmware includes communication between both boards using GBT protocol via redundant multi-Gbps Optic links powered by GTX, GTH and GTY Gigabit transceivers. Both firmwares allow read out of the TileCal PMT data, control of the on-detector electronics interfaced with the Daughterboard and remote reconfiguration of the Daughterboards and on-detector FPGAs and their respective configuration memories (PROMs). The development included digital design on different Xilinx evaluation boards (VC707, KC705, and KU115) before moving on to prototypes of the developed hardware.

• Testing and Debugging Demonstrator Read-Out Link and Control Board (Daughterboard): Different parts and components of the electronics design for the Daughterboard revisions 3, 4, 5 and 6 were tested. Among others, the tests performed included voltage noise levels of the developed board and interfaced cards, flash/EEPROM radiation tolerance, stability of the communication via the optic links, pedestal stability, charge injection and additional electronic noise. Texas instruments CDCE and CERN GBTx chips clock qualities, in addition to different CERN GBTx chip configurations were studied. The Daughterboard functionalities were also tested with all the upgrade system in testbeam sessions at the SPS at CERN. A testbench for debugging and qualify the Phase-II Daughterboards during development and production phase was put into place with the relevant off- and on-detector electronics. Additionally, a suite of python scripts for running the different tests by communicating the Tile-PPr thought IPBUS and a custom solution based on a Raspberry Pi to test/program/control/fuse the GBTx chips utilized on the Daughterboard were developed.

• Radiation tests for Daughterboard: The revisions 5 and 6 of TileCal Daughterboards were tested for Total Ionizing Dose (TID), Non-Ionizing Energy losses (NIEL), Single Event Latch-ups (SELs) and Single Event Upsets (SEUs) to qualify the electronics components used for the HL-LHC radiation environment. The TID and NIEL included the components of the board and different models of SFP+. The SEU tests characterized the Single Event Errors (SEEs) and the Single Event Latch-Ups (SELs) on the Microsemi ProASIC, Kintex Ultrascale and Kintex Ultrascale+ FPGAs used on the boards and evaluated the recovery strategies in case of non-recoverable errors.

• Upgrade, service and maintenance of the TileCal Legacy Digitizer boards: Tasks for Upgrade of Stockholm testbench for TileCal Digitizer Boards have involved migrating the testbench to a modern FPGA technology. As part of Stockholm University contribution to TileCal, different tests are done to the Digitizer Boards in order to certify them for detector operations. Tasks include the testbench tests and debugging the bad parts of the board in order to be able to repair when possible.

• Diploma Thesis: Energy Loss Behavior due to gluonic radiation in Gamma – Jet events in proton-proton collisions at 14 TeV in ALICE Detectors. Using Root – Aliroot software framework the energy loss due to gluonic radiation in Gamma – Jet events was obtained and analyzed by simulating p-p@14TeV events in PYTHIA. Jets were reconstructed with a properly calibrated cone reconstruction method that estimated background energy with ideal calorimeter and tracking, using PHOS and TPC ALICE detectors respectively. Energy vs transversal momentum, multiplicity and transversal pedestal energy of Jets were obtained. Diploma Dissertation. Faculty of Nuclear Physics, Higher Institute of Technologies and Applied Sciences (InSTEC), July, 2008. Supervisor: Arian Abrahantes Quintana.

• Software for Scientific Instrumentation: Multiple software were developed for scientific instrumentation in multiple programming languages such as LabView, C# and Visual Basic mainly for data acquisition systems such as data logger device which included the control of all the features of the device by USB interface as well as the acquisition of the data saved in the device. Additionally, it was developed the data acquisition software for the Laser Densitometer LD-01, which included the whole control of the device, the data acquisition, analysis and graph of the electrophoresis patterns for protein concentration in blood samples and the report of the results.

• Microelectronics for Scientific Instrumentation: Firmware development for took place using ANSI C Compilers and FPGA programming mainly for data acquisition systems. It was developed a firmware for Voltage Data logger DL-01, which controls the all the actions of the device as well as communication by USB or RS232 interface with a PC. Additionally, it was developed a firmware for a Laser Densitometer Device, which controlled the movement of a motor moving a laser while sampling the intensity absorbed by a sensor with a PIC’s ADC. It was developed a firmware for a Low Therapy Laser Device FISSER SMART, which consisted in the firmwares for a so called “base” that controlled applicators and for the applicators. Additionally, a firmware for Zone Dosimeters was developed, which consisted in the control of High Voltage of the detector, counting pulses of the detector, adjusting the characteristic curve of the detector, calibration of the device, screen, keyboard and alarms.

• Calibration and Certification of Equipment. Calibration tasksof the equipment developed at CEADEN were performed. The zone dosimeters DZG98 and DZG10 High Voltage were serviced and calibrated as well as the detectors units were characterized and adjusted in order to get the Certificate of Calibration emitted by CPHR, Cuba. The Laser of applicators of the FISSER SMART devices was serviced and calibrated. As member of the Quality Control of Instrumentation Department of CEADEN verification tasks for the Low Laser Therapy Equipment FISSER21 production were performed.
