Overview of the CUSP experiment as installed in the AD hall in CERN. Antiprotons are accepted from the top of the picture and transferred to the MUSASHI antiproton trap. After subsequenst stacking of around 5 antiproton bunches they are antiprotons are transeferred to the CUSP trap (the white box), where they are mixed with positrons to create antihydrogen. The positrons for this are provided by the positron trap and RGS system (on the right of the figure) and transferred to the CUSP setup.
Overview of the positron system. On the right the edge of the rare gas system (RGS) gan be seen, in which positrons are created in a 22Na source. From the RGS system positrons are transferred to the blue magnet with the cylindrical liquid Helium vessel on top. Positrons stay in the magnet for ~30 second before being transferred around two 90 degree bents to the CUSP magnet which is the white box in the middle left.

Image of the 70 million positrons extracted from the CUSP trap onto an MCP detector. A 10 fold improvement in positron intensity compared to the 2011 campaign. Positrons were also accumulated 10 times faster as compared to last years campaign. Both improvements lead to a higher antihydrogen production rate.
