Tibet$^\prime$s Window on Primordial Gravitational Waves

TL;DR

AliCPT is a ground-based Chinese experiment designed to detect primordial gravitational waves through CMB B-mode polarization, representing a significant step in China’s gravitational wave research efforts.

Contribution

This paper introduces the AliCPT project, China's first CMB experiment dedicated to primordial gravitational wave detection, highlighting its goals and collaborative nature.

Findings

AliCPT is in the construction phase with planned commissioning in 2019.

It aims to measure B-mode polarization of the CMB to detect PGWs.

The project involves international collaboration with over fifteen institutions.

Abstract

As an essential part of China’s Gravitational Waves Program, the Ali CMB Polarization Telescope (AliCPT) is a ground-based experiment aiming at the Primordial Gravitational Waves (PGWs) by measuring B-mode polarization of Cosmic Microwave Background (CMB). First proposed in 2014 and currently in fast construction phase, AliCPT is China’s first CMB project that plans for commissioning in 2019. Led by the Institute of High Energy Physics (IHEP) under the Chinese Academy of Sciences (CAS), the project is a worldwide collaboration of more than fifteen universities and research institutes. Ali CMB Project is briefly introduced.
