Muon tomography with Resistive Plate Chambers for geological characterization

Muon tomography is one of several fields of applied physics that have witnessed the successful use of particle detection based on Resistive Plate Chambers (RPC). In this work, we report on an innovative project concerning transmission muography for geological characterization. For this purpose, a muon telescope built of four RPC planes was mounted on an adjustable structure and the telescope's response to atmos...

Cochlear hair cell regeneration based on stem cells: A systematic review

According to the World Health Organization (WHO), by 2050 at least 700 million people will need access to hearing care and hearing rehabilitation services. The search for cell or gene therapies has been intensifying, and stem cell therapy looks a promising candidate to support hearing regeneration and reduce these numbers. The aim of this study is to provide an overview of current advances in stem cellbased the...

Outdoor systems performance and upgrade

Over the last two decades, the possibility of using RPCs in outdoors systems has increased considerably. Our group has participated in this effort by installing several systems and continues to work on their optimization, while simultaneously studying and developing new approaches that can use RPCs in outdoor applications. In particular, four detectors were deployed in the field at the Pierre Auger Observatory ...

The SHiP timing detector based on MRPC

Multi-purpose trigger system for medium particle detector devices

We report on an architecture of a multi-purpose trigger system based on inexpensive and off-the-shelf modules, with logic implemented in three levels, that can be used in a variety of small/medium systems just by writing a few registers using the accompanying software. The developed trigger algorithms are described in Very High Speed Integrated Circuits (VHSIC) Hardware Description Language (VHDL) and implement...

The trigger system of a large area RPC TOF-tracker muon telescope

The TOF-tracker concept, the simultaneous measurement of accurate time and bi dimensional space coordinates in a single gaseous detector, has been previously demonstrated based on Resistive Plate Chamber (RPC) technology. Recently, a larger area, 1550 × 1250 mm2 , RPC detector has been built. Signals are induced on metallic strips located in each side of the RPC active volume and coupled to both charge-sensitiv...

Data acquisition and laser scanning synchronism in SS-OCT — An experimental app...

Optical Coherence Tomography (OCT) is a high-resolution, non-invasive and contactless imaging technique based on optical interferometry. After the Time Domain (TD) and the Spatially Encoded Frequency Domain (SEFD), the Swept-Source (SS) OCT, also known as Time Encoded Frequency Domain (TEFD) OCT, is the latest technology available. It is based on a fast wavelength-sweeping of a narrow laser line over the bandwi...

Trigger system for a large area RPC TOF-tracker

The TOF-tracker concept, the simultaneous measurement of accurate time and bi-dimensional space coordinates in a single gaseous detector, has been previously demonstrated. Recently, a larger area, 1550×1250 mm 2 , RPC detector has been constructed. Signals are induced in metallic strips located in each side of the RPC active volume and coupled to both charge-sensitive and timing circuits, that can be used to ge...

A large area TOF-tracker device based on multi-gap Resistive Plate Chambers

The TOF-tracker concept, the simultaneous measurement of accurate time and bi-dimensional space coordinates in a single gaseous detector, has been previously demonstrated. The detector yielded a time resolution of 77 ps σ along with a bi-dimensional position resolution of 38 μm σ over a full active area of 60 × 60 mm2. In here, we report about a large area, 1550 × 1250 mm2, TOF-tracker device, tested by trackin...
