+ * All Orange cryostats are now equiped with an [automatic liquid nitrogen fill] |
+ * A new rotatable sample stick for [MA15] solves the problem of bad thermal contact |
+ at minimum temperature [details in German|http://lns00/ldmwiki/Wiki.jsp?page=Markus15Mar08] |
+ * The heater stage of the APD was replaced. It can now be reliably controlled over the |
+ full temperature range (20 K ... 450 K). [details in German|http://lns00/ldmwiki/Wiki.jsp?page=Markus24Apr08] |

+ !July ... August 2007 |
+ |
+ * An [automatic liquid nitrogen fill] mechanism for Orange cryostats has been developed |
+ * To prevent leaks on the o-rings of the needle valve feed throughs on [MA15], heaters |
+ with thermostats have been installed. |
+ |
+ !January ... April 2007 |
+ |
+ * The needle valves of [MA09], [MA11], [MA02] and [VARIOX] haven been [motorized|NeedleValveController]. |
+ * A cold leak on [ORI3] was repaired. |
+ * [MA09] and [ORI2] have still some very small leak into the main vacuum. |
+ They have to be pumped continuosly. |
+ * The temperature reading on [DIL1] has been changed from the AVS |
+ to a more modern, better resistance bridge (LakeShore 370) |
+ * [DIL2] can now be used with the so called [weak link|Dil2WeakLink]. This is a |
+ sample holder with a weak thermal link to the mixing chamber, allowing |
+ access to temperature range from 0.06 K up to 2 K with the same setup. |
+ * For every neutron scattering instrument, a set of |
+ [standard sample environment equipment|DeviceListPerInstrument] has been defined. |
+ Proposers have to select from this list, or to check the feasibilty with |
+ a SINQ contact person, if they want to use non-standard equipment. |
+ |
+ !Dec 2005 ... Aug 2006 |
+ |
+ * [SEA|SeaHelp] (Sample Environment Application), the new software for sample environment |
+ control will be installed on all instruments. |
+ * The orange cryostats needle valves have been modified to be driven |
+ by a [DC-Motor|NeedleValveController] instead of air pressure. A new |
+ [needle valve controller] has been developed, allowing to change the cooling |
+ power remotely. |
+ * The new dilution fridge [DIL2] was tested in the [MA15] cryomagnet. |
+ It can also be used in [MA11], [MA09] and [MA02]. |
+ * The dilution fridge [DIL1] runs now also in [MA02], the |
+ 1.8 Tesla horizontal field cryomagnet. |
+ * The [He-Gas|HeGasPanel] network in the SINQ halls has been reactivated. |
+ No more Helium gas bottles are needed. |
+ * There is now a semi-automatic [filling station for Liquid Nitrogen|LN2FillingStation]. |
+ * The AMOR furnace has now computer control. |
