BASE has kept a shot of antiprotons trapped for more than one year: it is the longest-lived, coldest, known baryonic antimatter object in the Universe

The commissioning of ELENA, a new antiproton deceleration ring, has begun

In a paper published today in Nature, BASE reports the most precise comparison of the charge-to-mass ratio of the proton to the antiproton

First direct high-precision measurement of the proton’s magnetic moment sets the stage for BASE

The ATRAP experiment presents most precise measurement yet of the antiproton magnetic moment
