Radio Observations of Meteors

Abstract : in this post we want to present some results obtained with our meteoric scattering radio reception system (Meteor RF Scattering Receiving System). We aimed the antenna in the direction of the Graves radar at an angle of about 50 ° and collected the data for a few days. …

Meteor RF Scattering Receiving System

Abstract : in this post we want to describe a “radar-astronomy” project. By exploiting the reflection capacity of radio pulses by meteor trails, it is possible to study their characteristics and number with radar techniques. At an amateur level it is practically impossible, even for legal reasons, to have adequate …

A simple 11.2 GHz RadioTelescope (SW part)

Abstract : In this post we continue the description of our diy microwave radio telescope. In the first part: A simple 11.2 GHz RadioTelescope (HW Part) we have described the hardware part of the instrument, including the parabolic reflector antenna, the LNB block and the receiver. Now we take care …

A simple 11.2 GHz RadioTelescope (HW part)

Abstract : In this post we describe the construction of a small amateur radio telescope operating at the frequency of 11.2 GHz. The construction of the radio telescope takes advantage of the satellite TV market which has made it easy and cheap to find parabolic reflector antennas with relative illuminator …

Measurement of the Milky Way Rotation

Abstract : In this post we want to continue the study of the structure of our galaxy made using the emission at 21 cm of neutral hydrogen and described in the previous post : Milky Way Structure detected with the 21 cm Neutral-Hydrogen Emission. In particular, we want to exploit …

GNURadio Software for the 21 cm Neutral-Hydrogen Line

Abstract : After the previous posts on the horn antenna (Horn Antenna for the 21cm Neutral-Hydrogen Line) and on the receiver (Low-Noise SDR-Based Receiver for the 21cm Neutral-Hydrogen Line) in this post we briefly describe the Linux GNURadio application and its use for receiving the 21 cm emission of neutral …

A Low-Noise SDR-Based Receiver for the 21 cm Neutral-Hydrogen Line

Abstract : after the article on the pyramidal horn antenna : Horn Antenna for the 21cm Neutral-Hydrogen Line, we now pass to describe the design, construction and analysis of the hardware system for receiving the 21cm radio-emission of neutral hydrogen. Design What we intend to create is a receiver centered on …

Dye Laser DIY

Abstract : In this post we want to exploit the “freshly built” nitrogen laser (DIY Nitrogen TEA Laser) as a source of excitation for a dye laser. The dye laser is super-radiant and therefore can operate, under the right conditions, even without a resonant cavity. By focusing on the cuvette …

DIY Nitrogen TEA Laser

Abstract : in the cover image the homebuilt TEA nitrogen laser in use at PhyscsOpenLab. The entire laser is ‘open air’ and is built into an aluminum / iron chassis with brass electrodes. The triggering spark gap is visible in the right side while the transverse discharge along the electrodes …

CERN DIY Particle Detector

Abstract : in this post we describe the construction and testing of the “DIY Particle Detector” developed at the CERN S’Cool LAB. It is a detector based on the BPX61 photodiode (mainly for alpha particles) and on the BPW34 photodiode (mainly for beta particles). The detector uses easily available and …
