The President of Kazakhstan, Nursultan Nazarbayev, visited ECL Laboratories
The President of Kazakhstan, Nursultan Nazarbayev, visited ECL laboratories. During his visit, Dr Baurzhan Alzhanov, Dr Ainur Koshkinbayeva and Dr Aliya Nurmukhanbetova explained the recent successes of developing cryogenic detectors, running the coldest place in Kazakhstan, mK Cryogenic facility, and installation of the fast telescope at Assy-Turgen.
Installation of the telescope
The next stage of development of the ECL project – installation of the telescope in the gorge of Assy-Turgen. The telescope is designed to register the process of development of a supernova in the optical range by “catching” gamma-ray bursts. We are trying to build the foundation of the research that has been conducted in the country for many years. The telescope is not a record in size, but is among the fastest in control. There are forty of them in the world, our telescope is Forty-first, will be included in the existing network of telescopes to study the early stage of the creation of the Universe. Its images will be used not only by scientists from Kazakhstan, but from the whole world! It is controlled remotely and on-site online. It will also be available for kazakh students for training as future astrophysicist.
ECL 2018 Autumn Workshop
ECL hosted two guests Prof. Blake D.Sherwin from Cambridge university, UK and Prof. Xuelei Chen from National Astronomical Observatories, Chinese Academy of Sciences.
Prof. Sherwin has deep studying about Cosmic Microwave Backgrounds. during his visit from ECL, he gave two talk with teh titles of «Seeing the beginning:the Cosmic Microwave Background and what it can tell us about our Universe» and «CMB Lensing: Fundamental Physics from Maps of the Invisible».
In his first talk, he discussed The way we can find out about the origin, composition, and ultimate fate of the universe by studying the CMB. In his second talk, he discussed about recent measurements of CMB lensing and their scientific implications. He explained why upcoming measurements of the CMB lensing signal, with experiments such as AdvancedACT and Simons Observatory, will be remarkably powerful probes of cosmology and also he explained why delensing – removing the lensing effect to reveal the primordial sky – is crucial for the future of CMB cosmology.
in his first talk, he had an overview on the major cosmology-related research institutes in mainland China, which includes the Chinese Academy of Science institutes as well as universities. He also described some on-going projects, including the DAMPE dark matter satellite, the PANDAX dark matter search experiment, the FAST telescope, the Tianlai experiment. He also described some future projects, such as the Ali-CPT experiment, the QiTai Telescope (QTT), the Discovering the Sky at Longest wavelength lunar satellite array, the China Space Station Telescope, etc. China is also involved in a number of international collaboration projects, including the SKA and TMT.
In his second talk, he talked about the first stars and galaxies formed at the end of cosmic dark age, the gas surrounding them get ionized by their radiation, forming ionized bubbles. These bubbles grow until they finally the whole Universe is reionized. After reviewing this general picture of reionization, He described his model of “neutral islands”, which are large under-dense regions ionized at a later stage of the epoch of reionization. He applied the excursion set theory of large scale structure to this problem and developed analytical and semi-numerical models for reionization. He then discussed the 21cm signatures for the cosmic dawn and epoch of reionization, and also our lunar orbit array project which is designed to probe the EoR.
ECL visit to Paris Center for Cosmological Physics
In the frame of collaboration with APC laboratory, ECL team worked in together with Paris cosmology research group to test different types of mm range to optical bands microwave kinetic inductance detectors (MKIDs) and participated in data analyses. During the visit at APC laboratory, ECL team visited Paris Observatory and learned about fabrication of microelectronic chips such as MKIDs.
WOLTE 13 2018, Sorrento, Italy
Dr Mehdi Shafiee with his team Marzhan Nekbalanova and Zhaksylyk kazykenov presented results of developing Microwave Kinetics Inductance detectors with the papers title of “Microwave Kinetic Inductance Detectors”, “Electronic Readout System for Microwave Kinetic Inductance Detectors” and “Noise Studying of Microwave Kinetic Inductance Detectors” at 13th Workshop on Low Temperature Electronics, WOLTE-13, September 10 – 13, 2018 in Sorrento, Italy.
Microwave Kinetic Inductance Detectors (MKIDs) are superconducting sensors that can measure energy and number of incident photons at the same time. The goal of the research program is to design, realize and test MKIDs in order to measure the photon (from sub-mm to X-Ray) energy and its quantity and arrival time for astronomy studies at ECL.
ICEC27-ICMC 2018, Oxford, United Kingdom
Baurzhan Alzhanov participated ICEC27-ICMC 2018 that took place on Monday, 3rd September, 2018 – Friday, 7th September, 2018 on research topic “The cryogenic detector for cosmology observation”.
He presented the implementation of Kinetic Inductance Detectors (MKID) for mm/submm astronomy purposes in our cryocooler at Energetic Cosmos Laboratory (ECL). We have used the robust cryocooler 106 Shasta from HPD Company. The refrigerator can cool down the temperature to 30 mK. In this report, we described our experiences about milli-kelvin refrigerator, implementation challenges of MKIDs and evaluation results.
ECL in the news
Microwave Kinetic Inductance detectors ( MKID) are used for capturing and characterizing mysterious cosmic explosions and bursts.
Marzhan Bekbalanova is working on the readout system of these detectors that uses FPGA to perform digital signal processing.
Baurzhan Alzhanov explains why we need an Adiabatic Demagnetization Refrigertor (ADR) for the MKIDs.

Trip to Assi Turgen:
On 13th-17th of November ECL members and Nazarbayev University SST (Physics) Master’s student Magzhan Kistaubayev visited Tien-Shan Astronomy Observatory. We had a collaborative work on short exposure observations with Electron Multiplied CCD (EMCCD) Cameras and tested GRB alerts receipt from NASA’s Swift spacecraft via GRB Coordinate Network.
