6. Ultrasensitive Cold-Electron Bolometer
Abstract : The Cold-Electron Bolometer (CEB) is an ultrasensitive device designed for the detection of cosmic microwave background radiation. The key to its sensitivity is the electron cooling of the absorber by the superconductor-insulator-normal metal (SIN) tunnel junction. READ MORE

7. 3D Electron Microscopy Methods and Applications : Structures from Atomic Scale to Mesoscale
Abstract : The crystal structure determines the physical properties of a material. The structure can be analysed at different levels, from atomic level, mesoscale level, all the way up to the macroscale level. READ MORE

8. Studies on high brightness electron beams for short pulses and free electron laser
Abstract : Accelerator based lightsources are one of the most powerful tools today for producing high intensity radiation at very short wavelengths. While synchrotron storage rings provide a high average brilliance in a wide wavelength range, the next generation of lightsources aim towards producing ultra-short pulses in the X-ray regime.

9. Electron energization in near-Earth space : Studies of kinetic scales using multi-spacecraft data
Abstract : Plasma, a gas of charged particles exhibiting collective behavior, is everywhere in the Universe. The heating of plasma to millions of degrees and acceleration of charged particles to very high energies has been observed in many astrophysical environments. How and where the heating and acceleration occur is in many cases unclear. READ MORE

10. Modeling of Electron Cooling : Theory, Data and Applications
Abstract : The Vlasov technique is used to model the electron cooling force. Limitations of the applicability of the method is obtained by considering the perturbations of the electron plasma. READ MORE
