Beamline to HHT

(return)

Introduction

Cave HHT is where plasma physics experiments take place. Contact person is Dmitry Varentsov.

Beams

In 2018 and 2019 no experiments are foreseen in HHT. In 2020 there will be an experiment.

Optics

Three MIRKO optics files were send by Sebastian in April 2018. Thy differ by the positions of magnets. The latest one was used to generate this LSA input (through MADX channel), but it was exchanged in 2019 (scroll down the page):

During the Dry Run in September 2019 it was found that the present optics does not allow to transport protons with energies above 2 GeV, while 4 GeV protons will be used for 2020 experiments. Dmitry Varentsov send updated values:

Please find below initial settings of the HHT beam line matched for the PRIOR experiments next year.
The values are given for protons, E = 4.0 GeV.
The first value is the effective field (G * L) and the second value in braces is the pole tip field.
The last quadruplet (HHTQQ4) does not exist yet but shall be added in the end of the year: the magnets will arrive in December.

GTE1QD12 :=  -1.30000 ( -0.140 T)
GTE2QT11 :=   2.80000 (  0.182 T)
GTE2QT12 :=  -4.80000 ( -0.312 T)
GTE2QT13 :=   2.70000 (  0.176 T)
GTH1QD11 :=   2.88400 (  0.187 T)
GTH1QD12 :=  -2.26400 ( -0.147 T)
GHHTQD11 :=   6.33700 (  0.411 T)
GHHTQD12 :=  -5.19900 ( -0.338 T)
GHHTQD21 :=  -2.26946 ( -0.245 T)
GHHTQD22 :=   7.75875 (  0.504 T)
GHHTQT31 :=   3.38000 (  0.365 T)
GHHTQT32 :=   7.31366 (  0.475 T)
GHHTQT33 :=  -9.06919 ( -0.465 T)

This optics looks like that:

And te LSA files are here:

Sinde September 2019 this is STANDARD HHT optics.
