Laboratory realization of relativistic pair-plasma beams Open
Relativistic electron-positron plasmas are ubiquitous in extreme astrophysical environments such as black holes and neutron star magnetospheres, where accretion-powered jets and pulsar winds are expected to be enriched with such pair plasm…

Jets and Jet Substructure at Future Colliders Open
Even though jet substructure was not an original design consideration for the Large Hadron Collider (LHC) experiments, it has emerged as an essential tool for the current physics program. We examine the role of jet substructure on the moti…

Design of the readout IC for the CDF SVX-II silicon strip detector Open
Future colliding beam runs at Fermi National Accelerator Laboratory will involve bunch spacings of protons and antiprotons at 132 ns intervals. Due to finite processing time, a pipelined architecture is needed to store events until a trigg…

Radiation hardness studies of AMS HV-CMOS 350 nm prototype chip HVStripV1 Open
CMOS active pixel sensors are being investigated for their potential use in the ATLAS inner tracker upgrade at the HL-LHC. The new inner tracker will have to handle a significant increase in luminosity while maintaining a sufficient signal…

Tagging $b$ quarks without tracks using an Artificial Neural Network algorithm Open
Pixel detectors currently in use by high energy physics experiments such as ATLAS, CMS, LHCb, etc., are critical systems for tagging $B$ hadrons within particle jets. However, the performance of standard tagging algorithms begins to fall i…

Charge collection studies in irradiated HV-CMOS particle detectors Open
Charge collection properties of particle detectors made in HV-CMOS technology were investigated before and after irradiation with reactor neutrons. Two different sensor types were designed and processed in 180 and 350 nm technology by AMS.…

Radiation hardness of two CMOS prototypes for the ATLAS HL-LHC upgrade project. Open
The LHC luminosity upgrade, known as the High Luminosity LHC (HL-LHC), will require the replacement of the existing silicon strip tracker and the transistion radiation tracker. Although a baseline design for this tracker exists the ATLAS c…
