 ====== BPM (Beam Position Monitor) ======
-===== Libera =====
+===== Libera Platform B =====
+The Libera is a data acquisition and beam position processor system used for the BPM systems in different accelerators and transfer lines. It was developed by the slovenian company [[https://www.i-tech.si|Instrumentation Technologies]] and was adapted and enhanced for FAIR applications as an in-kind contribution. It is a modular [[https://en.wikipedia.org/wiki/MicroTCA|MicroTCA]] based system used in different configurations for the particular requirements of the BPM systems for different accelerators at GSI and FAIR.
+{{ :instruments:bpm:libera_platform_b.jpg?nolink&400 |Libera Plaform B}}
+==== Libera Platform B features ====
+Each of our Liberas has some features which are common for each application:
+  * 19“, 2U, 310mm depth
+  * MTCA based (non standard)
+  * COMe Controller Board
+  * FTRN slot
+  * Acts as FEC
+  * Up to 4 BPM modules
+==== Libera family tree ====
+For GSI/FAIR beam diagnostics there are four types of applications:
+  * Libera Hadron for Circular Machines
+  * Libera Hadron for Circular Machines + Closed Orbit Feedback (COFB)
+  * Libera Hadron for HEBT
+  * Libera Single Pass H (SPH)
+{{ :instruments:bpm:libera_family_tree_1_0.png?direct&400 |Libera family tree @GSI & FAIR}}
+Another application for the Libera at GSI/FAIR is the Low Level RF (LLRF) controlling. It is under responsibilty of GSI's LRF department and not further treated in this article.
+The usabilty of a Libera for a certain application depends from the hardware configuration and installed software. We have three types of hardware configurations:
+  * Libera Hadron for ESR, HESR & HEBT
+  * Libera Hadron + COFB for SIS18 & SIS100
+  * Libera SPH for p-Linac
+=== ESR-/ HESR-/ HEBT-Libera (Libera Hadron) ===
+{{ :instruments:bpm:libera_hadron_hebt_front.jpg?direct&600 |}}
+== Inter Connection Board (ICB) ==
+  * COM Express MSC C6B-7S
+  * Intel Core i5-3610ME
+  * 16GB DDR3-1600
+  * GbE, USB 2.0, DVI-A
+  * ARM BMC
+  * FPGA
+=== SIS18- /SIS100-Libera (Libera Hadron + COFB) ===
+{{ :instruments:bpm:libera_hadron_cofb_front.jpg?direct&600 |}}
+=== p-Linac-Libera (Libera SPH) ===
+{{ :instruments:bpm:libera_sph_front.jpg?direct&600 |}}
+For the retrofit the Liberas are also now in use for GSI's SIS18 and ESR.
