841. SLAC T-510: A beam-line experiment of radio emission from particle cascades in the presence of a magnetic field

Oral contribution

Radio detection is a technique of great interest for detecting ultra-high energy cosmic rays. Models of radio emission from extensive air showers, based solely on principles of classical electrodynamics, were developed in recent years. The SLAC T-510 experiment was conducted in January-February of 2014 using an electron beam to validate these models in a laboratory environment. Secondary...

Oral contribution

LOPES was a digital, phased antenna array located at the site of KASCADE-Grande in Karlsruhe, Germany. Triggered by the particle-detector array of KASCADE, LOPES measured the radio signal of air showers. By an interferometric, offline combination of the signals measured by different antennas, LOPES was able to enhance the signal-to-noise ratio. This lowered the detection threshold...

Oral contribution

TARA (Telescope Array Radar) is a cosmic ray radar detection experiment co-located with the Telescope Array conventional surface scintillation detector (SD) and fluorescence telescope detector (FD) near Delta, UT. The TARA detector combines a 40 kW transmitter and high gain transmitting antenna which broadcasts the radar carrier over the SD array and in the FD field of view to a 250 MS/s DAQ...

645. High-precision measurements of extensive air showers with the SKA

Oral contribution

As of 2020, the Square Kilometre Array will constitute the world's largest radio telescope, offering unprecedented capabilities for a diverse science programme in radio astronomy. At the same time, the SKA will be ideally suited to detect extensive air showers initiated by cosmic rays in the Earth's atmosphere via their pulsed radio emission. With its very dense and uniform antenna spacing on...

531. The lunar Askaryan technique with the Square Kilometre Array

Oral contribution

The lunar Askaryan technique is a method to study the highest-energy cosmic rays, and their predicted counterparts, the ultra-high-energy neutrinos. By observing the Moon with a radio telescope, and searching for the characteristic nanosecond-scale Askaryan pulses emitted when a high-energy particle interacts in the outer layers of the Moon, the visible lunar surface can be used as a detection...

357. Radio emission from ultra-high energy cosmic-ray showers after reflecting on the Earth.

CR-EX

Oral contribution

We present the calculation of coherent radio pulses emitted by extensive air showers induced by ultra-high energy cosmic rays accounting for reflection on the Earth's surface. Our work is motivated by the detection of pulsed events in the ANITA experiment compatible with cosmic-ray origin after reflection on the ice cap at the South Pole. The properties of the radiation are discussed...
