We would like to discuss the possibility of further improvement of the ET/CE sensitivity at high frequencies using parametric amplification techniques. There are several regimes so we can combine those ideas to make one discussion session.

In this poster we describe a feasible length sensing and control scheme for the low frequency interferometers of the Einstein Telescope (ET-LF) along with the techniques used to optimise several optical parameters, including the length of the recycling cavities and the modulation frequencies, using two numerical interferometer simulation packages: Optickle and Finesse. The investigations have sug ... More

We present the current status of the seismic studies using the seismometers developed by the Warsaw group. We show the measurements of the sensitivity of the instruments. The instruments have been installed at the Ksiaz Castle site in Poland, and currently we are installing at two additional sites: the Matra mine in Hungary, and in Sos Ennatos mine in Sardinia. We will present the preliminary resu ... More

The sensitivity of the gravitational-wave detector KAGRA, at present under construction, will be limited by quantum noise in a large fraction of its spectrum. The most promising technique to increase the detector sensitivity is the injection of squeezed states of light, where the squeezing angle is rotated by a Fabry-P ́erot filter cavity. One of the main issues in the filter cavity design and re ... More

To match requirements of ET and possible cryogenic upgrades to aLIGO, thermal noise in highly-reflective mirror coatings has to be significanlty reduced. Due to a high refractive index and low mechanical loss at cryogenic temperatures, amorphous silicon (aSi) is a very promising material. The absorption of highly-reflective aSi/SiO2 coatings at 1550nm has been shown to be about 1000ppm and theref ... More

Silicon is a candidate material for future gravitational wave detectors being operated at cryogenic temperatures. Operating silicon in the near infrared might be a solution for low noise operation. However, several optical properties of silicon are not known in the near infrared and at cryogenic temperatures. We present current results on the investigation of optical, electronical as well as me ... More

Some of the many technical challenges that the Einstein Telescope interferometers will present fall into the domain of controls. In particular, the ET-LF interferometer will have to suppress vast seismic motion at 1 Hz, while leaving the quantum noise limited sensitivity at 10 Hz as undisturbed as possible. In this poster we will present the early results from our longitudinal control noise invest ... More

A spinning neutron star is a source of continuous gravitational waves, if its mass distribution is non-axisymmetric. Such asymmetry can be caused by various instabilities and deformations (e.g. Andersson, 2003, Gondek-Rosi ́ska et al. 2003). We have performed calculations of the gravitational waves background produced by the ensemble of rotating neutron stars in the Milky Way. In our calculat ... More
