On the ATLAS top mass measurements and the potential for stealth stop contamination Open
The discovery of the stop — the Supersymmetric partner of the top quark — is a key goal of the physics program enabled by the Large Hadron Collider. Although much of the accessible parameter space has already been probed, all current searc…

The first probe of a FLASH proton beam by PET Open
The recently observed FLASH effect related to high doses delivered with high rates has the potential to revolutionize radiation cancer therapy if promising results are confirmed and an underlying mechanism understood. Comprehensive measure…

The first PET glimpse of a proton FLASH beam Open
We demonstrate the first ever recorded positron-emission tomography (PET) imaging and dosimetry of a FLASH proton beam at the Proton Center of the MD Anderson Cancer Center. Two scintillating LYSO crystal arrays, read out by silicon photom…

Limited-angle TOF-PET for intraoperative surgical applications: proof of concept and first experimental data Open
The intraoperative gamma probe (IPG) based on single gamma-ray detection remains the current gold standard modality for sentinel lymph node identification and tumor removal in cancer patients. However, IPGs do not meet the <5% false negati…

Performance of a Front End prototype ASIC for picosecond precision time measurements with LGAD sensors Open
For the High-Luminosity phase of LHC, the ATLAS experiment is proposing the addition of a High Granularity Timing Detector (HGTD) in the forward region to mitigate the effects of the increased pile-up. The chosen detection technology is Lo…

Development of a high-resolution and high efficiency Single Photon detector for studying cardiovascular diseases in mice Open
SPECT systems using pinhole apertures permit radiolabeled molecular distributions to be imaged in vivo in small animals. Nevertheless studying cardiovascular diseases by means of small animal models is very challenging. Specifically, submi…

A novel TOF-PET MRI detector for diagnosis and follow up of the prostate cancer Open
Prostate cancer is the most common disease in men and the second leading cause of death from cancer. Generic large imaging instruments used in cancer diagnosis have sensitivity, spatial resolution, and contrast inadequate for the task of i…
