To do that, CERN built a new device, the Antiproton Decelerator, which uses electric and magnetic fields to slow the particles from near lightspeed to about one-tenth of that, he explained.

This time the trainers called the problem a " decelerator " muscle in his back, which is a new one even for Saberhagen but appears to have finally put the brakes on his 17-year career.

KMB turned to its double deckers, but again none was suitable for the steep inclination of the route . so KMB fitted a Cummins LT10 280 hp engine and a manual decelerator into a 9.7m MCW Metrobus.

NASA's Low Density Supersonic Decelerator ( LDSD ) program is testing out some of these new devices and in April 2012 performed a trial run on a rocket sled test to replicate the forces a supersonic spacecraft would experience prior to landing.
25.
The disc-shaped LDSD uses an inflatable structure called the Supersonic Inflatable Aerodynamic Decelerator ( SIAD ), which is essentially a donut-shaped balloon, to create atmospheric drag in order to decelerate the vehicle before deploying a large supersonic parachute.

By riding the decelerator sled himself, in his 29th and last ride at Holloman Air Force Base in New Mexico, Stapp demonstrated that a human can withstand at least 46.2 g ( in the forward position, with adequate harnessing ).

For landers that are even heavier than the Curiosity rover ( which required a 4.5 meter ( 15 feet ) diameter aeroshell ), engineers are developing a combination rigid-inflatable Low-Density Supersonic Decelerator that could be 8 meters ( 28 feet ) in diameter.

As there is no hope of completing the original mission, the crew increase acceleration even more; they need to leave the Milky Way altogether in order to reach a region where the local gas density, and the concomitant radiation hazard, are low enough that they can repair the decelerator.

The SkyJump did not qualify as the world's highest " bungee " as it is not strictly speaking a bungee jump, but instead what is referred to as a'Decelerator-Descent'jump, using a steel cable and decelerator system, rather than an elastic rope.
