The Antiproton Decelerator (AD) at CERN operates for physics since 2000. It delivers low energy antiprotons for production and study of antihydrogen, for atomic physics and for medical research. Two beam cooling systems, stochastic and electron, play key role in AD operation. They make transverse and longitudinal emittances small, which is obligatory condition for beam deceleration without losses, as well for physics. The machine performance is reviewed, along with plans for the future. Significant improvement of intensity and emittances of the beam delivered to the experiments could be achieved with the addition of a small ring suitable for further deceleration and cooling. The details of this new extra low energy antiproton ring (ELENA) and its status are presented.

In the course of Tevatron Run II (2001-2007) improvements of antiproton production have been one of major contributors into the collider luminosity growth. Commissioning of Recycler ring in 2004 and making electron cooling operational in 2005 freed Antiproton source from a necessity to keep large stack in Accumulator and allowed us to boost antiproton production. That resulted in doubling average antiproton production during last two years. The paper discusses improvements and upgrades of the Antiproton source during last two years and future developments aimed on further stacking improvements.

New efforts are under way at Fermilab to increase the rate of the antiproton production. This program includes the machine optics optimization in order to improve mixing and help stochastic cooling. The new lattice has been implemented in May of this year. Results will be discussed, as well as some aspects of model development and lattice measurements.
