Digital Interferometer for Study of X and Gamma Ray Emissions by Lightning

 

The UPC Lightning Research Group is looking for a qualified Ph.D. student within the European project H2020 SAINT project: "Science And INnovation with Thunderstorms".

Context:

In the last 20 years it has been discovered that thunderstorms can produce transient beams of very energetic radiation escaping into space, known as Terrestrial Gamma-Ray Flashes. At the same time, lightning leaders in negative polarity cloud-to-ground flashes have been observed to produce X-rays at the ground. To study this phenomenon in much more detail than before, a new space mission "Atmosphere-Space Interactions Monitor" (ASIM) on the International Space Station is about to start in 2017. The general objective of the Ph.D. is to increase our knowledge of the emission of energetic radiation and processes during lightning flashes.

The UPC group has developed extensive infrastructure for study of lightning, thunderstorms and their energetic and radio emissions as well as high-voltage experimental facilities and computational models (see some of our facilities in this link)

 

Tasks:

1) The student will develop a VHF digital interferometer. This system uses the phase differences of arriving pulses to multiple antennas to compute the direction to emission sources at the micro/nanosecond scale during the processes in lightning flashes. Such system will provide much higher spatial and temporal resolution than the 3D Lightning Mapping Array of the UPC group.

2) By deploying the new interferometer in field campaigns, the student will use the data to study the lightning processes at the moment of energetic emissions detected at the ground or from space, and publish the research.

3) Secondments (research visits of a few months) are scheduled with high-voltage laboratory DENA in Spain, University of Bath (UK) and the Danish Technical University (DTU).

4) The student will participate in SAINT workshops and collaborations and present the work at conferences.

 

Besides the specific objectives, the project will contribute to the general knowledge of lightning and thunderstorms useful for lightning protection, warning and detection.

Investigation of corona and leader properties useful for lightning protection


DENA is looking for a qualified Ph.D. student within the European project H2020 SAINT project: "Science And INnovation with Thunderstorms". The student will be supervised by the UPC Lightning Research Group.

DENA (INGESCO group) is a lightning protection company. DENA manufactures lightning protection components, lightning warning systems and high voltage tests. In addition, Labelec is the high voltage laboratory of DENA. The laboratory is an accredited for testing of lightning protection components. The laboratory has two voltage impulse generators of 1 MV and 2.5 MV respectively and an impulse current generator of 100 kA currently being upgraded to 200 kA. The market of the laboratory includes lightning protection of wind turbines and aircraft.

More information at: www.labelec.es

Context:

Current external lightning protection is just based on air termination systems, down conductors and grounding. The most common air terminations are lightning rods and conductor meshes. All are only conceived to receive lightning attachments but not getting any additional information.

The objective of this project is to investigate streamer and leader properties to be used in lightning protection. This research will be applied to design ‘smart’ lightning rods able to detect conditions for corona and leader inception and to obtain data from the lightning events. These smart lightning rods will be the next generation of lightning protection.

SAINT will provide a unique environment for this project thanks to the different objects of the researchers and the collaborations in the consortium.

 

Tasks:

1)      High voltage laboratory experiments to investigate the conditions of corona inception and the transition to leader discharge. Optical and electromagnetic measurements will be conducted in order to find suitable methods to be included in field experiments.

2)      Laboratory data will be also used to feed numerical models of coronas and leader transition. Bot, laboratory and simulations will be used to determine the required measurement system to include in lightning protection systems.

3)      Proposal and development of the detection and measurement systems.

4)      Field investigations at the UPC group instrumented tower.

 

Some experiments and modelling will be done in collaboration with other Ph.D. students in the SAINT project.

 

Candidates: Shall have skills in high voltage engineering, instrumentation and/or discharge physics.
